is what the behaviour of the primitive code is. In the interpreter #= will short-circuit (avoid the send) if both the receiver and the argument are either a SmallInteger or a Float. In the JIT the primitive will not fail if the receiver and argument are both SmallIntegers or Floats or if the receiver is a Float and the argument is an Integer, but will fail if the receiver is a SmallInteger and the argument is a Float.
