"export" is widely misunderstood. It doesn't mean separate compilation
of templates, and I'd be surprised if it sees much use even when more
compilers support it. Herb Sutter has done some interesting articles on
his experiences with the Comeau compiler, which now supports "export",
and my impression is that the complications it raises outweigh the
benefits (which apparently don't even result in quicker compilation!)

Not that this should dictate .h/.cc policy in any way, I'm just being a
C++ bore again!
