The future C++ template model in gcc?

I think this could be taken as a description of an implementation
strategy of the "export" keyword (even though the text probably
predates the export keyword). Supporting the export keyword is
certainly a goal, since it is a very valuable feature, and mandated by
the standard.

I'd be also curious as to whether anybody has fragments of an
implementation of exported templates; since nobody has spoken up so
far, the answer is probably "no".
