Feature or enhancement

list.pop currently calls list_ass_slice which contains some extra caculations not relevant for list.pop. With a direct implementation the cases for small lists is improved.

Pitch

The gain for the improved cases is in the 10% to 30% range.

Previous discussion

This came out of tests performed related to #94508
