Language design mistake.

And we'll fix it by makeing more widespread.

Let's change that.  Mixing ints and floats should to
automagical conversion, it should cause an exception.  That's
no more disruptive that changing the meaning of the "/"
operator, and it's far more in line with the spirit of not
converting operands to make operators happy.

That's one opinion.  I feel that in an OO language the objects
should determine the meaning of the operators.
