I am aware of the method suggested by
gaal. I usually do not use it because I almost always wrap the regex up with an 'if'. Throw in a my function and it starts to get messy.
# Ugly to me...
if (my ($this, $that, $some, $other) = $line =~ /(this).*(that).*(some
+).*(other)/) {
do_it();
};
# Better, I think...
if ($line =~ /(this).*(that).*(some).*(other)/) {
my ($this, $that, $some, $other) = ($1, $2, $3, $4);
do_it();
}
This business doesn't DWYM:
my ( $this, $that, $some, $other, $foo, $bar, $baz ) = ( $1 .. $+ );
The magical string incrementer is summoned to build a list of strings starting with the first capture, ending with the last.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
