If you know you're dealing with either ints or floats,
which is true in the vast majority of cases, then you
know that / will always perform float division.

As for why int/int should yield float and not some
other type, float is alreay special -- it's built-in
and has syntactic support in the form of literals.
It's the most obvious choice.

If a version of Python were ever to exist in which
floating-point literals produced Decimals instead of
floats, then int/int would produce a Decimal.
