When it's in a state where it has some closure (e.g. parsing 
declarations works, even if you can't actually use those parameters and 
sema never hears of it or treats it as non-templates), and you've 
written a few test cases, submit it for review. It has to do something 
useful (at least for testability), it should not crash the compiler 
under any circumstances.

I think a big discussion is in order before touching sema of templates 
anyway. We have to plan the template engine.
