Batuhan Taskaya opened a duplicate issue #42454.  Since it includes PR-23496, with some review, and at least as much discussion, I am closing this issue, contrary to normal policy.

Worthwhile? Batuhan found about 100000 constant slices in 3200 PyPI packages, and 3-50% speedup.

Rémi asked "Couldn't [slices] hash like a tuple (start, stop, step)?"
Batuhad used the tuple analogy - hashability and hash depends on components.  See PR for details.

Josh: the PR defines TYPE_SLICE as ':'.
