 yes. but?

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

What I am suggesting again is remove the keyword constexpr. make const do that.
 Just to remember C++ was already like that before constexpr. In c++ const could be used as constant expressions.
What C++ could not ensure is that global variables would have a compile time initialization.
In C all global variables are initialized in compile time.
For local variables like...
 const int i = ... ;
the compiler must evaluate the initialization expression if it can be computed in compile time then i is "constexpr" does not matter if it have or not the constexpr keyword.
