alias_set proposal (N4150)

Hi all,

I am looking into providing fine grained (no)aliasing information in a heavily templatized piece of c++ code.

I noticed proposal N4150 that seems to provide the tweaks I am looking for:

Unfortunately, it seems not to be part of the upcoming C++17.

Does there exist an implementation for clang/llvm that implements this proposal ?
Or is there an alternative proposal (with implementation) that made it into llvm and/or the standard ?

Thanks ,
