I believe the chose "if constexpr" because it doesn't 
significantly alter language semantics and compiler internals. 
C++ already had #ifdef, so the I personally don't find a need for 
more than "if constexpr". The concept of "if constexpr" also has 
a valuable advantage when writing a library: the compiler can 
type check all branches.

The primary advantage, IMHO, for D to have "static if" rather 
than "if constexpr" is that a static for loop becomes trivial to 
implement. So this is an advantage the D is likely to retain.
