Still adding D features, I see!

constexpr if looks a lot like static if to me.

I don't think it is like static if. AFAIK it cannot turn off 
member fields and it cannot turn off static_asserts.  "if 
constexpr" is primarily for preventing instantiation issues, so 
it does not introduce a separate compilation stage like in D.

In C++ this will fail to compile:

if constexpr(false){
    static_assert(false);
}
