See http://bugs.python.org/issue9574 for a bit more context. To begin with,
it's not at all clear what *should* be allowed. If "1 + 2j" is valid, what
about "+ 2j"? How about "+ 2"? What about things like "+1.0 + -2.3j"?
Ultimately, I closed that issue because the proposed change seemed like
unnecessary code churn, and there wasn't a clear consensus that the change was
desirable (or even what that change should be). If it ain't broke, etc.
