Const / static allows for "immediate" ASM instruction generation: which means the value is known at compile time so it can compare it directly inline as opposed to the overhead of comparing it to a labeled memory address. It's generally good practice whenever possible.

Isn't that constexpr?

  Isn’t constexpr c++-only?

what?!?! static doesn't imply the value can be known, only in some cases where its not modified in that compilation unit (which is trivial to detect with SSA) const is something else.
