I've got the following code snippet: 

    my %mapping = ( ARRAY  => '@',
                    HASH   => '%',
                    SCALAR => '$',
#                    GLOB   => '?',
#                    REF    => '?',
#                    CODE   => '?',
                  );
    if (grep { $_ eq $type } keys %mapping) {
        if (isa($_[0], $type)) {
            return eval "$mapping{$type}{$_[0]}";
        } else {
            return @_;
        }
    } else {
        return ();
    }

The idea is to allow for someone to pass in either a list or a listref and the function will handle it transparently. (Don't ask why ... it's one of those creature feep things.)

Now, I originally wrote this as a bunch of if-elsif-elsif-else's, but realized that they were all the same, except for the $@% character. (Which brings me to a side question - how do I handle REF, CODE, and GLOB in this fashion?) I figure I should be doing some sort of eval here, but have no idea what.

Help?
