Enums are free and global variables may have cache misses

An enum isn't guaranteed to be embedded in the instruction
stream,
there's still plenty of opportunities for cache misses.
enum FOO = true;
static if (FOO) {
doThis();
} else {
doThat();
}
No need for enum to be embedded in the instruction stream.
Because it won't be. The else block just doesn't get compiled
in.
Of course, I just meant that when reading a global or an enum,
enum isn't necessarily cheaper. static if f.t.w.
