I don’t know where you got that idea. The binary ops are consistent - they aren’t constrained by register size like in previous PHP versions, but they’re still completely consistent. > and once you hit the > promotion breakpoint working with that integer is a lot slower. It’s slower, yes, but that hardly matters.
