Good call on the arity! The reason I didn't want to give them a () prototype is because I will find it convenient to call them like: 
$enumClass->$enumName

sometimes. I was getting ready to respond, it occurred to me that -> notation ignores prototypes! Yay! I get the best of both words. I guess it helps to talk things out!

Thanks!

    Just be careful you don't shadow one of your packages with a sub of the same name. 

    use strict;
use warnings;

package Foo;

sub bar { print "Foo::bar\n"; }

package Bar;

sub bar { print "Bar::bar\n"; }

package main;

sub Foo { "Bar" }

Foo->bar();
"Foo"->bar();

exit 0;

__END__

    The problem isn't that you're missing the prototype. The problem is that you're missing parens. Omitting parens leads to a lot of problem. Simply put, omitting parens is broken. You must be prepared to add them when necessary.
