I really don't see the problem here.  While it might be slightly
convenient to sink cmath into math, it _is_ documented on the math
module page that cmath exists and what it is for.

As to _why_ you should need to know this, I submit that if you're using
complex numbers in your programs, you really ought to know about the
cmath module and when/how you should use it.

I look forward to the timbot's scholarly explanation.
