Node.js or Erlang
... the guy who actually wrote node. I think that will help give you a better idea where node is at, and where it's going.

How do I change the working directory in Python?
...
cdunn2001's lightweight decorator-based answer is the ideal approach for modern Python. The above answer demonstrates why. Never call os.chdir() outside of a context manager, unless you think you know what you're doing. (You probably don't.)

... course I wasn't hoping that Count or Where would "somehow" pick up on the idea that my data is sorted, and run a binary search instead of a plain "check everything" search. All I was hoping for was some improvement due to the better branch prediction (see the link inside my question), but as it tur...
