Having NAN be a seperate type wouldn't help. If x needs to be an int, it
can't be a separate NAN object because that's the wrong type.
If ints had a NAN value, then rationals would automatically also get a
NAN value, simply by using NAN/1. That's similar to the way that the
complex type automatically gets NANs, on the basis that either the real
or imaginary part can be a float NAN:
py> complex(1, float('nan'))
(1+nanj)
