There is a misunderstanding here. The goal is to replace the 
implementation of the builtin AA with a template implementation. Right 
now there are some "magic" pieces of the AA that are helped by the 
compiler. If we can do this all in a template library, then the syntax 
doesn't change at all, but now you have better abilities to customize 
the builtin AAs, or use more specialized templates in some cases.
