TO DO list:

1. Our test_cmath is out of date relative to CPython:                 self.rAssertAlmostEqual(0., z.imag) -> self.assertEqual(0., z.imag)
in test_cmath_matches_math.

2. test_complex failed to detect my error complex("inf") not valid.

3. cmath.java hyp/trig functions could be more efficient. e.g. sin(z) calls Math.exp twice for same values. Possibly needless testing for nan/inf.

4. Object comparison is a maze of twisty passages.

Some are definitely not in scope for this issue, and some are -- I'm parking them here as I noticed them in the course of the work.
