think of catch as some function. I don't really care about the try/catch, I've used the code as a starting point for my experiments!

UPDATE: But why is catch executed before try ? 
#! /usr/bin/perl -l

use strict ;
use warnings ;

    sub try (&@) {
        my($try,$catch) = @_;
        eval { &$try };
        if ($@) {
            $catch;
        }
    }
    sub catch (&) { &{$_[0]} }

    try {
        die "phooey";
    } catch {
        /phooey/ and print "unphooey\n";
    };
__END__
output:
Use of uninitialized value in pattern match (m//) at ./tc.pl line 18

UPDATE: of course, its an argument which is evaluated first!! thnx JavaFan
