Being fond of guessing syntax and inventing dangerous constructs today I have been using null values as keys in my hashes. Whats the goosy with that then, I assume it is allowed so you can catch bad key look ups $hash->{''}="a value"; I have found this handy when calling function refs that are stored in hashes &$hash{$params->{action}}->(). I tried using autoload but my sub dereferance messed up with null values and did't call nuthin until i introduced this null key. Also can I push null values onto arrays I tried and I don't think it worked.
