I don't like it.

When I see obj.func(), to me, func() is a member function. Why 
should I spend any time trying to work out whether it's a member 
function or a free function? It doesn't make sense to me.

If it's really a free function, I'd like that to be more 
explicit..

e..g

obj.\func().   (or something like that ..where \ means its a free 
function)
