To make question less boring and pure and to be interested, I'll
present a new question as:
give 2 strings, how to judge whether they have common
character?
or the next question, give 3/4/... strings, what to do?

Following this, we can write 3 strings solution naturally, but not for
any number of strings problem.

That is short for:
my @subset = grep( $_ =~ /^$_.+$/, @strings );
So you are trying to match the current element of @strings against the
current element of @strings plus one character. And since the current
element of @strings cannot have more characters than the current element
of @strings it will never match.
What you want is:
foreach my $element ( @array ) {
print "$element\n";
my @subset = grep /^$element.+$/, @strings;

You're using $_ for two purposes, as your ordinary loop variable, and as
the variable in grep. You're hoping to use a different variable, but of
course, it'll use the same value twice: as the variable for grep.
The fix is to use a different loop variable:
foreach my $r (@array) {
print "$r\n";
my @subset = grep(/^$r.+$/, @strings);
...
Although you could use a copy of the loop variable:
foreach (@array) {
print "$_\n";
my $r = $_;
my @subset = grep(/^$r.+$/, @strings);

Just to be clear, I'm talking about using the variable within the package
when strict is enabled.
Within the package where this is declared, all is fine if I use the package name.

Here is cut & paste code sample:
---------------------------------------
package FunStuff;
use strict;
our $IwannaBeApackageGlobal = "use strict then";
$FunStuff::IwannaBeApackageGlobal3 = "use strict then = 3";
print $IwannaBeApackageGlobal,"\n"; # works with strict
print $FunStuff::IwannaBeApackageGlobal3,"\n"; # works with strict
print $IwannaBeApackageGlobal3,"\n"; # does not work with strict
----------------------------------------------------------------------------------
Error: Variable "$IwannaBeApackageGlobal3" is not imported at [...] line 10.
Why do I get this error when printing $FunStuff::IwannaBeApackageGlobal3 as just
$IwannaBeApackageGlobal3. Without strict, this works fine.

Outside of the package, all is ALSO fine if you use the package name!
(this is why you should alway prefer lexical variables over package
variables, except when you can't. i.e. package variables open you
up to "action at a distance" type of bugs.

Works because it was declared with our().

Works because it uses the fully qualified name.

Because that is what "strict vars" is supposed to do.
That is, $IwannaBeApackageGlobal3
was not declared via "our" or "use vars"
and
was not localized via "my()"
and
was not fully qualified
perldoc strict
...
"strict vars"
This generates a compile‐time error if you access a variable that
wasn’t declared via "our" or "use vars", localized via "my()", or
wasn’t fully qualified.

Subject: negate a match in regex
Message-Id: <368a732a-e8ab-42e5-b32d-1aa91fbeaf0b@k41g2000yqn.googlegroups.com>
Hi All,
I have a script that I convert xml tags to html. like "<" I convert to
"<" and so on.
after the conversion I need to capture the information inside the tag.
let take for example the string "<abcd>: which is equivalent to
"<abcd>".
I tried to capture the "abcd" which can be different from tag to tag
in the following way:
/\<\;([^\&\gt\;]*)/
like match "<" and then match anything that is not ">".
the thing is that it doesn't work on all tags for some reason and I
was wondering on a principal base if doing a [^somestring] suppose to
work ?
Thanks.

No, using [^string] wont work as you're expecting. Just like
[string] doesn't match 'string' but only one of the letters s, t, r,
i, n, or g [^stirng] just matches one letter which isn't in 'string'.
What you need is a negative look-ahead (?!string). Read 'perldoc
perlre' for the explanation of it.

You probably want something like:
/<(.*?)>/

Yes, you did that by following a moronic pop theory. The purpose of
this message is to tell you, that you should have decades of study of
multiple deciplines in history, economics, psychology, sociology, to
be immune to the lots of pop theories that float about especially
today with the internet.
let me explain why the pop theory you fell for breaks apart with
respect to the namespace issue here in this thread.
lacking namespace is not due to some ratio of perceived benefit
divided by perceived pain.
The benefit is huge, practical, and undeniable, the pain to adopt the
namespace fix is almost non-existant, because any such solution will
obvious be done in a backward compatible way. If the solution is
provided, the pain at max is just like a version upgrade. Java, Perl,
and all langs goes thru major upgrade every few years.
there are social reasions and technical reasons why langs lacking much
needed namespace took so long to fix. Social reason being, as others
has said in this thread, for examples: compatibilities issues in the
case of javascript's browser/server situation. In the case of Scheme
lisp, there's the issue of committee consensus and the RnRS standard.
You can't just have someone created a namespace implementation and
have every other Scheme lisp adopt it. As far as i know, namespace has
been in lots of Scheme implementations for long. The problem is
getting it into RnRs. The situation in Emacs lisp, at least partly
have to do with lack of developers, and partly have to do with Richard
Stallman. First, you need someone capable enough to actually implement
it as some sort of proof of concept, then you have to pass thru
Stallman himself, else you get XEmacs fork situation, which
significantly hurled GNU Emacs forward for the past about 15 years. In
the case of PHP, i suppose the primary reason is that it works without
namespace so far. PHP lang is mostly hack. The lang is so messy that
namespace is not just one thing that needs to be fixed. All the above
reasons, are of social one. There are undoubtly some technical reasons
too. I don't have compiler knowledge so i can't say what, but to say
the least, that creating a namespace in a existing lang that is widely
used in the industry is not something a average computer science
graduate can do.
The above are ugly, perhaps complex, real world facts. It's not some
pop fucking book about some pop pereciveness of some ratios.
one can go on analyze the perceived benefit and pain about the
namespace issue on each language specifically. You can see how it
doesn't apply. But going in detail on this'd be waste of time. If you
spend your time to debunk pop theories, play their game, the
scientific establishment would go no where.
There are quite a lot pop books on the market, they usually sells.
Their audience is the mass market. They have little scientific value.
They are not valued by any expert in any field. Most of them cannot be
invalidated in any way. This does not mean pop theory, pop psychology,
wisdoms, or anything not dry science, are all bullshit. Ultimately,
there's no magic rule that can tell you which is which. The degree and
quality of you or the masses's judgement, ultimately depends on your
education level. That is why, general education is so important, in
every nation and culture, while it's little talked about only because
its so obvious, so plain.
here's another pop book you might like:
=E2=80=A2 Book Review: Patterns of Software
http://xahlee.org/PageTwo_dir/Personal_dir/bookReviewRichardGabriel.html
this one is published a decade ago by a lisp dignitary.
Its theory of programing and software engineering is poetry and
taoism.
It suggests that C will be the last lang.
