I notice that some of your operators return rvalue references. It seems
that everybody tries that, and eventually goes back to returning plain
rvalues (see the discussion about boost.multiprecision for instance).

Seems easiest to wait for C++14, where you want constexpr in front of
every function.

It seems that MS decided to break the library ABI at every release and the
core ABI almost never, and the change you are asking for would break core
