I come from assembly -- 'a' and 'A' are *not* the same.
indents -- I already used them; finding a language that gave them the
same importance I did was incredible.
exceptions -- Python uses them, true, but I don't have to in my own code
(I do, but that's besides the point).
lambdas -- they work just fine for my needs.

It's only an error if it's documented that way and, more importantly,
thought of that way. The re module is a good example: if it can't find
what you're looking for it returns None -- it does *not* raise a
I see get_clock() the same way: I need a clock that does xyz... None?
Okay, there isn't one.
