With constexpr you could enforce that the expression you assign is
compile-time evaluated. That's while constexpr would make sense.

 

This is already the default in C for file scope variables ...

 They must be optimized away by the compiler and the linker, constexpr
not. And most compile time constants that are constexpr'd in C++ are
local variables. So constexpr makes sense at least for local variables.
 

If you are afraid your constant is not constant expression put a static_assert. Then remove.
And this makes sense only in local scope.
(C++ is a TOTAL mess. const in C++ already could be used n constant expression)
