Mathematicians also have a tendency to use single letter variables and
often escape into non-ASCII character sets as well. <wink>

Perhaps it's worth pointing out that pylint complains about most/many
infix operations if you don't surround the operator with white space.
And, complex expressions work just fine with white space around the
operator:

>>> 1 + 2j
(1+2j)

Personally, I'm agnostic to the proposed change. I don't use complex
numbers in my work, and I suspect that creating complex numbers from
strings is an extremely small corner case.
