It will be an issue with a future BSD. It seems to take a long time
before any of my libm improvements are committed. At the moment, bde
and I are probably the only people with sinpi(x) in our libm.
I do, however, anticipate that glibc will get these functions in
the future as portions of ISO/IEC TS 18661-4 have already been
implemented.

In the 5 minutes that I've searched, I've found https://bugs.python.org/
but there are no instructions on how to submit a bug report.
