By declaring the hash with my(), you are making it lexical, and not
accessible from other file/package scopes. You need to either declare
it with an explicit package name:

	%main::hash = ();

or, with recent perls, use our():

	our %hash;

and in either case, then refer to it from other packages as:

	$main::hash{'foo'} = 'bar';

That is, assuming you declare package namespaces in your modules :-).

Cheers,
