My understanding is that nothing *actually* goes wrong here (the hw just
treats both things as the type of the first arg), but it seems entirely
reasonable for the simulator to warn us because usually it would be due
to us screwing up, and it'll save us some time some day when we look at
the generated code ourselves and wonder why there's a float there.
