Nick just said it's a bug that cmath type checks are too strict.

I'm not so sure about that. cmath just uses PyArg_ParseTuple with "D" which itself relies upon PyComplex_AsCComplex().

D (complex) [Py_complex] Convert a Python complex number to a C Py_complex structure.

In order to fix the bug the code in PyComplex_AsCComplex() must be altered to support float as return type from complex(). That's a major change.
