If we decided to go with automatic registration, would you suggest putting
the registration templates inside the anonimous namespace?

By the way, Daniel James suggested an idea which I didn't like first, but,
come to think about it, might be not that bad after all:

We could create a compile-time GUID template, and register against its
instantiations.  Some of the outputs of the Guidgen are quite suitable for
instantiation of such a template.  This class could be passed from the
function using sizeof() in four steps...

Probably an overkill, though.  And would probably introduce noticable
compile-time performance penalty...

Besides, is GUID a portable concept?
