New declaration for me.

For the compiler (with optimisation on) it doesn't matter if you use a friend or an inline non-virtual class member

Isn't it amazing how much abstraction you can get for free? The compiler translates both examples as if you just wrote this:

Very interesting! I've not used the friend declaration before (I don't think it was very prevalent when I coding in C++), so it's new to me. And looks a lot cleaner than having to resort to 'setter' and 'getter' type methods!
