Glad to be of service!  (But I was hoping you'd get rid of case too ;-)

	switch ([want]) {
	    'LIST'	{ @ret = &wrapped }
	    'SCALAR'	{ $ret = &wrapped }
	    &wrapped
	}

	switch ($num) {
	    0            { return 'zero' }
	    [2,4,6,8]    { return 'even' }
	    [1,3,4,7,9]  { return 'odd' }
	    /[A-F]/i     { return 'hex' }
	}

etc.
