What about something like this?:
%cat = (
'C[AEIOU]NWAY' => 'AAA',
'(?:BOSTON|CHICAGO)' => 'BBB',
'(?:LAS VEGAS|NEVADA)' => 'CCC',
'(?:DALLAS|AUSTIN)' => 'DDD',
'(?:NASHVILLE|M[AEIOU]MPHIS)' => 'EEE'
);
$var = "CHICAGO";
@keys = keys %cat;
$re = "(".join(")|(", @keys).")";
if ($var =~ /$re/o) {
for ( 1 .. @keys) {
print "$_:", $$_, " - ", $keys[$_-1], "\n" if defined $$_ }
}
Problems:
- It's not strict refs.
- it still loops on the number of matches (thought it only does one regexp match).
- I had to change all the '('s in the data to '(?:'.
I think the for loop could be replaced with one of the magical $+ or $- vars, but I couldn't find exactly the one I'm looking for - "The var that tells me how many of $1, $2 were defined in the last match".

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).
