"use strict" to catch errors in your code
An example of how to use Tie::RegexpHash could be:
use strict;
use warnings;
use Tie::RegexpHash;
my $regex1=qr/^\d+$/;
my $regex2=qr/^\D+$/;
my $regex3=qr/^.+$/;
my %functions;
tie %functions, 'Tie::RegexpHash';
%functions = (
$regex1 => sub {print "Number\n"},
$regex2 => sub {print "Not number\n"},
$regex3 => sub {print "Mixed\n"}
);
while (<>){
last if /^$/;
$functions{$_}->();
}
Hope this helps!

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).
