Subject: Re: Calling global method

I might expect (did expect, as a matter of fact) to be able to call 
such a method just by doing the following:

def somemodule::somemethod
   ::test()
end

That is, prefix the method name by a double colon as you would a 
constant defined outside of any module [1]. It doesn't work, though. 
Some mechanism like that would be awfully useful in certain cases (I've 
personally come across such a case in a real application), and could be 
implemented much less hackishly than Ruby currently allows. 
Specifically, what's needed is a way to access the top-level "module" 
within which methods are defined (or are they defined in Object by 
default?).

Failing that, see previous replies.

Constants and Variables."
