Writing the AA is NOT the problem, but I doubt we can get 
compatible enough to replace the built-in AA. Rather it'll 
require to deprecate a few built-in AA semantics and adding 
operator and literal extensions for the library type.
Hence the proposal to start with a HQ library AA and 
incrementally converge them.
