High performance applications that rely on non-reflexivity will still have an option of using ctypes.c_float type or NumPy.
Python could also provide IEEE-754 equality as a function (perhaps in "math"), something like: def ieee_equal (a, b): return a == b and not isnan (a) and not isnan (b) Of course, the definition of math.isnan cannot then be by checking its argument by comparison with itself - it would have to check the appropriate bits of the float representation.
