I think another angle of attack that AFAICT has been mostly overlooked
is for the compiler to recognize certain common template patterns, and
optimize away intermediate template instantiations that are not actually
necessary.  Not every template instantiation requires wholesale copying
of the AST.  I surmise certain patterns of templates could be profitably
turned into some kind of compile-time executed code.
