Why doesn't Typeof use decltype on VS 2013?
Probably because Typeof hasn't had a maintainer since before decltype. It doesn't appear to use decltype for any compiler.
I don't think it can. The semantics of BOOST_TYPEOF is that of: auto x = expr;
The semantics of decltype are quire different. For instance, auto and BOOST_TYPEOF and GCC's __typeof__ never deduce references -- always values. decltype on the other hand can deduce references.
As long as BOOST_TYPEOF is less precise than decltype it can be emulated, can it not?
