I'm using neither :) I'm just considering learning at the moment. > First of all, I don't know how it is in C++, but in D you rarely write > function declarations without definitions.

I was hoping that D could overcome this problem. Ah, one (maybe) final question: Is there an equivalent to friends in D (didn't see any in the docs)? If so, do they work with templates easily? In my style of programming, I very rarely use member functions (I think they are an atrocity in language design), so I create global functions for almost everything, and when they need to access to private members, I have the class declare the function as a friend. Does D support my style of programming? Here's a concrete example of something I'd like to do (pseudocode): class Foo { private int x; friend globalFun; } class Bar { private int y; friend globalFun; } void globalFun(ref Foo foo, ref Bar bar) { foo.x = bar.y; } Is there anything like this in D? Export sounds like the right thing, but can that be used in the example above, assuming that Foo and Bar are in separate modules?
