Peter Thomassen added the comment: I like your most recent suggestion, and updated the PR after fixing a typo ('Fractions') and making it more complete (complex numbers).

Semantically, they may be related, but the question here is whether the types are actually related.) ---------- _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue30803> _______________________________________
