No idea what makes you think so. Anyway C++ is beyond repair because it
conflates class-wide and specific types. Keeping them apart is essential to
the consistency of the types system.

I seek a better types system because of problems the current one causes,
like overuse of generics and run-time checks. I, as a programmer, need more
static checks, more reuse, far less debugging.

ARG's decisions are not influenced by the noise generated here in c.l.a.

Ideas are secondary to a vision of the language as a whole and the
direction it has to evolve. This is vision is absent now.
