Ok, I see what you're talking about. It has nothing to do with UFCS, it is D's
design decision to not have explicit friends, but to make everything in a module
implicitly a friend.
I think it's far superior to the explicit friend thing in C++.
I've never seen much cause for hiding things within the same module. It's not
like you're allowed to edit one part of the file and not touch another part.
