We don't need C++ for that. I can only speak for myself. I do not want to be in the meta-compiler business, and I do want proper tool support for templating.

It would make more sense for all the various values to be bundled together by type, so that a type is comprehensible as whole, quickly. Instead all the values are in separated property lists that cut across all the types. Worse, very similar or identical information to what is in this list is repeated, without any chance of consistency or error checking, all over the place.
