This code is in copy_reg.py from 1997:

def pickle_complex(c):
    return complex, (c.real, c.imag)

pickle(type(1j), pickle_complex, complex)

I'm not sure if the function pickle_complex() is
necessary, but it definitely seems that the line after
should be commented out or removed.  pickle_complex()
is not in the doc either.

(I was building WITHOUT_COMPLEX and found this problem.)

Without that line you can't pickle complex numbers. Maybe it
should fail gracefully if complex doesn't exist. Feel free
to check in a fix for that.

I'm rejecting this as invalid. Neal, if you disagree, just
reopen and assign to me.
