I think that it should be relatively simple to extend the Python integer
class to have a NaN flag, possibly by having a bit length of 0, and have
it follow the same rules for the handling of floating point NaN, i.e.
any mathematical operation on an iNaN returns an iNaN and any comparison
with one returns False.
How does it differ from float('nan')?
It is still an integer and would pass through any processing that
expected an integer as one, (with a value of iNaN).
Python is dynamically typed language. What is such processing that would
work with iNaN, but doesn't work with float('nan')?
