Schemer? That's a horrid name! What is up with google that they can't see what a terrible name it is? Does anyone want to hang out with ANYONE who is "scheming"? Google's own search for that word gives this definition: "Given to or involved in making secret and underhanded plans." And really, in this day and age that makes half of us wonder if we'd get on some eff'n homeland security watchlist on signup.
Considering their taste, they could go with 'pythonista'.
