Another couple ideas you might get some traction on are making
typeid() values be convertible back into typeof types iff CTFE.
That would let you use types as OOP class values in intermediate
structures while still turning them back into template args later.
Not sure just how realistic that

When I first saw C++ templates, I thought "what the hell is this black
magic", and had no idea how they worked. In fact, this was back before
STL, and I recall it was a set of templates
