in thread To module or not?

A follow up question might be: is there a way to have global variable shared between the main::space and the module::space so I don't have to keep passing the same values over and over? (I know, not a good idea, but just for the sake of discussion)

So, instead of:

#MAIN: my $foo = "aaaaaaa"; my $bar = "bbbbbb"; print add_strings ($foo, $bar);

Be able to just have:

#MAIN: my $foo = "aaaaaaa"; my $bar = "bbbbbb"; print add_strings (); #MODULE: our ($foo, $bar); #this might be make-believe add_strings { my $newstring = $foo . $bar; return ($newstring); }

    You could always reference $main::foo et al, but you'd have to use our $foo in main rather than my (lexicals not living in the symbol table and all).

    But yeah, not a good idea. Action at a distance, and what not.
