JavaScript 1.7 steals shamelessly from Python

A colleague shared a Planet GNOME article with me this morning about using the Thread.js library to fake threads and write Erlang-style concurrency in JavaScript. After briefly investigating said library, I must reluctantly admit that I didn't realize how much really cool stuff there is in JavaScript 1.7 -- much of which has been imported from Python: generators, iterators, and array comprehensions.

I keep hearing people complaining that JavaScript is becoming too much like Python, and I never understood what they were talking about. Now I do. I just don't understand what they're complaining about.
