I know...I don't like it either...the Dlang version auto-initializes.

I don't think so. The problem is that initialize() must be called after all the
static registrar objects have executed, and before the first method call.

With msvc, I could use init_seg. But I see no general solution. But I would be
delighted to be proven wrong.
