Perhaps it's just me and my personal coding style, but I find I tend to use hashes for a large variety of things involving user input and certain actions based upon that input, much likes a switch statement. So I often have things like 
$bar{foo}->() if( exists $bar{foo} );

And this always struck me as really fairly ugly, not to mention long. So does anyone have anyway to shorten that? I suppose you could do something like: 
$qux = $bar{foo};
$qux->() if $qux;

But that doesn't really gain anything.

This is a test
