Nice fix, and it holds up: checked against `seq[start:stop:step]`, the crossed-bound cases that used to produce a negative `LIMIT` now come back as `[]`. A couple of things worth considering: 1. A regression test would be great here. `test_xcom_get_with_slice` already compares against `["f", "o", "b"][key]`, so a few crossed-bound params (`slice(2, 1)` for the `start >= 0` branch, `slice(-2, 1)` for the `start < 0` branch) would pin it down and fail without the guards. 2. The same `start < 0` branch still returns the wrong window when `stop` overshoots the end: on a 5-item list, `seq[-2:6]` gives `['c', 'd', 'e']` instead of `['d', 'e']` (off by one, and present on main too, so not introduced here). It could be worth folding into this PR given the overlap -- This is an automated message from the Apache Git Service.
