I don't think it is too late for reification, but it does seem to be 
necessary to support both reified and non reified (erased) classes, and 
possibly classes where some but not all type parameters are reified. 
Primitive type parameters are unavoidably reified (as far as I can see), 
so not supporting reification for other types would be peculiar.
