the latest XRCed version requires you to annotate the
xrc in order to obtain the same effect which is not only tedious, but
as far as I can tell it also makes it impossible to round trip between
XRCed and wxFormBuilder.

True, and in a serious application I'd probably pass the map by
reference into the function. Still, it's rather likely that these copies
are optimized away by the compiler; this is what VC++ does, for instance.

Newbies learn, and the fundamental C++ lessons are usually

Assembly language is pretty easy to learn too. But is it a
