in reply to Implementing Dispatch Tables

This is an old post, but regarding your snippet ($disp_table{'not there'} || sub {})->(); why not do something like $disp_table{$some_key}->() if $some_key;?

It shouldn't error out for using an empty string. If your key is falsy (0 or undef), then it won't look it up.
