Hi,

I was wondering how to access a global function fn in ruby from a class which also defined a method fn. I have made a workaround by aliasing the function like so:

def fn
end

class Bar
    alias global_fn fn
    def fn
        # how to access the global fn here without the alias
        global_fn
    end
end

I'm looking for something along the lines of c++'s :: to access global scope but I can't seem to locate any information about it. I guess I don't know specifically what I'm looking for.
