As I indicated in an earlier response, there is some performance value to replacing the range function call with this (or other) syntactic sugar. It's my impression that adding stuff like this primarily for performance is nothing on the list ;-)

I wasn't arguing for its inclusion, just explaining that there is potentially more than a few characters of typing to be saved. (Someone asked if that was the only benefit of the proposal.)

FWIW, at least some compilers (Shed Skin, I believe, perhaps Cython and/or Pyrex as well) already treat range() as a builtin constant.
