Well if you really like the look of the switch type construct, TIMTOWTDI...

SubSwitch.pm

package SubSwitch;
use strict;

use base 'Exporter';
 
our @EXPORT_OK = qw(
   switch
   case
);
 
our $SubSwitch = undef;
 
sub switch
{
        my ($val, $func) = @_;
 
        local $SubSwitch = $val;
 
        $func->();
}
sub case
{
        my ($val, $func) = @_;
 
        if ($val ne $SubSwitch) { return; }
 
        $func->();
}
