I have a small nit inline, but I'm happy for you to fix that up and submit without re-review as the rest LGTM.
We add a third argument `step` to `!range` bang operator to make it with the same semantics as `range` in Python. `step` can be negative. `step` is 1 by default and `step` can't be 0. If `start` < `end` and `step` is negative, or `start` > `end` and `step` is positive, the result is an empty list.
