I hadn't have time to look at the proposal in detail.  I think it would
be good to have the standards committees review this.  I doubt you could
find consensus in the C++ for type system changes unless you have a
really good reason.  Have you considered how you could use the ARM
extensions from http://wg21.link/p0214r4 ?
