SPUG: Hash of subs Re: Hashes and subroutines

[Fred Morris]

Sure, I do it all the time.

%H = ( play => sub {}, that=> sub {}, funky=> sub{}, music=> sub{} );

&{$H{play}}('awb');

Somebody will point out how to do it without so many braces.

Maybe somebody will step up and show how to do it with the hash blessed and 
the subs as autoload methods. ;-) Too complicated for my needs though.
