I have a minor concern about certain corner cases with math.hypot and complex.__abs__, namely when one component is infinite and one is not a number.

as well, and FWIW, I personally agree with this convention. However, the math module’s documentation for both 2.6 and 3.1 states, “All functions return a quiet NaN if at least one of the args is NaN.”
Yes; this is a doc bug. Please could you open an issue on http://bugs.python.org ?
math.pow(1.0, nan) is another such exception to the rule. Perhaps the documentation should be updated to reflect this.
Yes, it should. Thanks! Mark
