"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 /^$/;
  $functions{$_}->();
}
