Thanks. Have updated the commit.

are currently computing at runtime.

Do you have any referenced to support your claim? IIRC all supported compilers treat static const int = ..literal..; as a compile-time constant.

If there is a reason to do the changes, it should ideally be enforced with a linter/tidy check, no?

@maflcko Oh, I didn't really check asm result of static const int... definitions. Now I see they are the same as constexpr int. Thank you and sorry for my unnecessary PR.
