Actually that would only determine if they do in the current version
of Perl. I suspect it is _unlikely_ that split() will ever change the
values of $& et al but until and unless it get's put into the
documentation of split() I wouldn't want to rely on it.

Seconded. I also advise against using any of the regex-related
variables as arguments to a subroutine without double quoting them to
avoid the undesirable aliasing.
sub do_something {
"Unexpected results" =~ /$/;
print shift,"\n";
}
"Expected results" =~ /$/;
print $`,"\n"; # Expected results
do_something($`); # Unexpected results
do_something("$`"); # Expected results

Not that I know of, but I've heard both Randal Schwartz and
Tom Christiansen say that they always use double quotes...
I'm of the "use double quotes only if you _need_ double quotes" camp,
because I'm just a Regular Guy and not a Genius Hacker.
The rules are different between those demographics. :-)
I need all the "brain cycles" available to solve the problem,
I don't have excess that I can spend on checking for edge cases.
The programmer's choice of quotes is a note to (him|her)self:
"interpolation or backslash escapes are here!"
or
'nothing special going on here'
Double quotes without interpolation or backslash escapes tricks
the maintenance programmer into spending more debugging time on
that string than is necessary.
(assuming a string of more than just a few characters)
> Using double quotes in a situation where single quotes could also

> be used is not a programming error.
But then you have to remember to analyse the situation everytime
you want to quote a string.
$re = "func\(\)";
print "matched [$1]\n" if /($re)/; # matches "func" without parens
Gets false matches with "", would have worked fine the 1st time with ''.
> It is a matter of style.
Yes, but that is what style choices are for.
Either to make debugging easier, or to reduce the chances of
inserting bugs in the first place.
The above-mentioned "rule" does both.

AOL. One IMHO legit reason to prefer double quotes is that ' and "
are more visually distinct than ` and '.
I'd argue the " vs. ' beef isn't in the same league as use strict,
test return value from open(), avoid C-style loops, and most others.

Some more examples of saying that "something special" is going
on when nothing special is going on:
m/RE/s; # when RE does not contain a dot
m/RE/m; # when RE does not contain ^ or $ anchors
printf "%s\n", 'Hello World'; # printf() w/same formatting as print()

I always use qx/prog/ instead of `prog` because it is more
visually distinct, so that reason isn't legit in _my_ code. :-)

Actually IIRC this turns out to be not so effcient which is why the
FAQ does not recommend it in "How do I efficiently match many regular
expressions at once?"
I can't be bothered to do some benchmarks now but if you search for
previous threads containing the string "How do I efficiently match
many regular expressions at once?" then no doubt you'll find some.

The 'guestbook' script (both the NMS and the original MSA one) have a
facility to send a message to someone when something was added to the
guestbook. I seem to recall the MSA one had the additional feature of
acting as an anonymous mail proxy for spammers.

Sounds plausible. Maybe an imported feature from Matt's formmail? :)

Whoops. I was confusing
split ' ';

Just to be sure, I cut and paste your code, and tried running it, with
no success. I'm not surprised, as I've been wondering all along if this
was a Windows issue. The problem is that this script is desitined to be
used by our customers eventually, and they are running on both windows
and unix, so I need to make it work on both, or there is no point in
releasing it. I guess I may have to resort to brute force methods, i.e.
manually create the directory structure that I want on disk, and then
look and see if add_file works any better...

did you read in the Archive::Tar documentation the paragraph that reads:
Although rich in features, it is known to not work on Win32
platforms. On those platforms, Archive::Tar will silently
and transparently fall back to the Archive::Tar::Win32
manpage. Please refer to that manpage if you are on a Win32
platform.

Or:

Of course all three have a syntax error*, but who cares about that. :)
* - the / in the closing tag should be escaped :)

I forgot to mention: if the code is to be used "in the wild", you should
consider a serious check, to see if the address matched is indeed a valid
one, I suggest you use Email::Valid in the match:
snippet:
-------------
use Email::Valid;
s!(mailto:(\S+))!Email::Valid->address($2) ? "<a href='$1'>$1</a>" : $1!eg;

(corrected the match-delimiter from / to !)
minor nitpick: that wouldn't match an address at the end of a line that
doesn't end in a newline.

Is the file a publicly available web page? In that case, displaying
non-obfuscated email addresses, with or without mailto links, is bad.

Can't answer this question; never saw a mathematician who works with
regular expressions. 1/5 ;-)
But in general, [with a few exceptions] mathematicians do not mind the
same word having different meanings in different contexts. Too few
words, too many things to work over....
[For an extreme example, 'less than' may have a different meaning if
written by a French.]
Hope this helps,
Ilya

Is it Python that made you forget all sane things? ;)

The module is still however very much a work in progress and there are
parts of the XSLT spec that are not completely supported. If you need a
wider range of features you might consider using XML::LibXSLT as
suggested by someone else.
