Spin works because it's a marketing term, and it implies manipulation of
the marketing message. Stuff we take for granted is lost on 99 44/100%
of the world, as in 'What do you mean there's no "Intel Inside" my brand
spanking new PowerMac G3? Why not? What gives?'
Perl's strengths will sell themselves to the right audience. It fits
the 'text hacking' slot, the 'sysadmin glue' slot as well as the 'excellent
ROI' slot. Those of us who use perl as duct tape tend not to think in
terms of ROI. Yet it can be equally important in selling all of perl.
Eric Raymond makes a good case in HtN that as [open source] software
matures, the soft factors become more important than the core technology.
Spin is a good example of one such soft factor.
Besides, spinning mostly perfect spheres can be fun! :-)

What about reinitialising the hash:
%hash = ();
Instead of local(), you're probably would be better off with my(). For
your own convenience, you should be programming with 'use strict' on
anyway :)

Thanks - that explains a lot. But doesn't that mean that by overloading
operators, you're very likely subjecting yourself to some nasty recursion?
I mean, what if your particular objects can be very conveniently
concatenated by using '.'? Do you have to avoid using '.' inside your
MyConcatenate() function, else it will recurse right back into MyConcatenate()
and so on and so on? What do people do to stop the recursion? Or do you
simply find Yet Another Way to skin the cat, avoiding the '.' operator
altogether? [1]

you have reached the limits of my knowledge of overload (which is close
to 0). i just knew that "" used . internally. how to stop recursive
overloading i can't answer. try using the c.l.p.moderated group and you
might reach a better audience who can help.
my weak gut feeling is that if you don't use the overload package in the
module which defines it, you get the builtin operator. otherwise it
would make no sense. read the overload docs for more on that.

No, unless you write
use overload '+' => sub {shift + shift};

I do not follow you. What is a difference of '.' and '+'? You did
not overload '+' as shown above, right? You probably add *contents*
of objects, not the references to objects.
A reasonable way to overload '.' is with (skipping ordering issues)
use overload '+' => sub {my ($a,$b) = @_; "$a" . "$b"};
And you original problem was that you overloaded '.' to *mean*
something else than concatenation. Do not. Preserving meaning *is*
important, as you discovered it yourself.

Exactly the opposite. `use overload' is not lexically scoped, it
modifies the behaviour of the package=class where it was executed.

I probably confused things by bringing '+' into the conversation. I overloaded
'+', and got exactly the behavior I wanted.

No, I overloaded '.' to mean concatenation. The problem is that the
MyConcatenate() function (which is called by the overloaded '.' ) has
other complexities that caused problems when it was called unexpectedly.
I guess my original confusion was because I thought that operators used
inside the module defining the class would *not* be overloaded themselves.
Or that ones called under the cover wouldn't be overloaded, or something
like that. I think Uri expressed the nature of my problem well, and I'm
now trying to figure out how to work around it.
I do appreciate all the input I've gotten.

Yes, it is the best Perl book.
"Programming Perl" is also the best Perl book.
So is "Learning Perl"; and "Perl Complete" comes pretty close.

This is exactly what you need (actually, you need SQL*Net and Pro*C).
(Be cautious when receiving the Oracle software -- when I installed
Oracle 7.3, my SQL*Net and Pro*C software came on the Oracle server CD,
with *nothing* (on the packing slip or CD-ROM) indicating that either of
these was present -- you just had to know that you were getting the right

Dag, that's a pretty good solution. I'm going to have to visit CPAN
again. Seems there's a module for everything.
So the question arises: How does one keep up with all the new modules that
can solve problems like this?
Ya gotta admit, that to the newbie a "How do FTP in Perl?" question does
not beget "libnet" without lots of research and poking around.
Is there a database of questions with module solutions?
Like:
Question: "How do I do FOO?"
Answer: Use the "HTTP::Foo" Module.
(No, I'm NOT talking about the search enigne on www.perl.com).
(No, I'm NOT talking about the Perl FAQ, either).

So you're recommending we just let everyone in to a room full of wild
animals with an axe, a lighter, and a bag of briquettes? You're going
to need to supply a lot of cheap beer for that to fly. Actually, maybe
not.

I was thinking about something a bit less Robert Bly :) Fine rare
scotches and around 100 taps, of course, I could stash some Bud for the

what about briquettes and LOX?. a professor in the midwest (this is a
well known true story on the web) lit briquettes which had been soaked
in LOX. each briquette had the power of a stick of dynamite. he also
converted a cheap hibachi slag in the order of seconds!

And people wonder why chemists are crazy. :) When I was in school we had
fun with all sorts of stuff. There will be no chemists allowed into the

That e is unnecessary unless you use single quotes as delimiters.
s':'$expr'eg;# need the e to force eval of right side
s/:/$expr/g; # right side is interpolated

Oh, that's right. I knew I didn't have it right but I couldn't
just remember how to say `subroutine' in Dutch.
Thanks for the correction.

Why not? After all, who's better qualified?

Subject: Strict and Global Variables
Message-Id: <Pine.SUN.3.95.981019184705.18799A-100000@caip.rutgers.edu>
Hello.
I'm trying to write a Perl script that is somewhat optimized for
speed. To this end, I'd like to use global variables. I'd also, however,
like to "use strict".
So, I was wondering if the way to have global variables while
satisfying strict was to both "my" and then "local" every global variable
at the outermost level of code. Like this:
#!/usr/local/bin/perl5 -w
use strict;
my $name; #satisfy strict
local $name; #make the variable visible throughout the entire program
Although globals are usually frowned upon, given that globals will
be used, is this practice acceptible (and will it work)?
Thank you,
Mike

What happened when your tried it? (I think this needs to be added as a
standard clpm abbreviation, WHWYTI).
If you want to use globals and also use strict the usual way it is done
is to use vars:
use strict;
use vars qw($put @your %globals $here);

Administrivia:
Special notice: in a few days, the new group comp.lang.perl.moderated
should be formed. I would rather not support two different groups, and I
know of no other plans to create a digested moderated group. This leaves
me with two options: 1) keep on with this group 2) change to the
moderated one.
If you have opinions on this, send them to
perl-users-request@ruby.oce.orst.edu.
The Perl-Users Digest is a retransmission of the USENET newsgroup
comp.lang.perl.misc. For subscription or unsubscription requests, send
the single line:
subscribe perl-users
or:
unsubscribe perl-users
to almanac@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.misc (and this Digest), send your
article to perl-users@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.announce, send your article to
clpa@perl.com.
To request back copies (available for a week or so), send your request
to almanac@ruby.oce.orst.edu with the command "send perl-users x.y",
where x is the volume number and y is the issue number.
The Meta-FAQ, an article containing information about the FAQ, is
available by requesting "send perl-users meta-faq". The real FAQ, as it
appeared last in the newsgroup, can be retrieved with the request "send
perl-users FAQ". Due to their sizes, neither the Meta-FAQ nor the FAQ
are included in the digest.
The "mini-FAQ", which is an updated version of the Meta-FAQ, is
available by requesting "send perl-users mini-faq". It appears twice
weekly in the group, but is not distributed in the digest.
For other requests pertaining to the digest, send mail to
perl-users-request@ruby.oce.orst.edu. Do not waste your time or mine
sending perl questions to the -request address, I don't have time to
answer them even if I did know the answer.
