constexpr keyword is unnecessary

I think constexpr keyword is unnecessary.
Anything you do with it could/should be done with const.

Even without const , one object like (struct point){.x=1, .y=0} is a 
constant in my view.

So, for instance, no need for (constexpr struct point){.x=1, .y=0} here.

The VLA could have been the motivation for a new keyword, but I don’t 
think it matters.

On the other hand, (static struct point){.x=1, .y=0} makes sense.

If constexpr were "no-storage" I think it would make sense but it is not.
