Either that or in each function that implements a mixed type
operation. I'm not sure what is better. I might do it in the
individual functions since I don't like the idea of checking for
specific types in the generic do_binary_op function. But inserting
the warning in a lot of functions is messy. So, I would probably just
not warn. What's the harm?

Yes, the same happens for mixed int/double and int/single operations.
But there, compatibility made the priority higher for implementing
mixed int/double operations, and mixed int/single is not much
different from mixed int/double, so those were done too.

I think you've found the reason that no one else has done this job.
It's just not that important and no one else has been motivated to do
it either.
