Research direction

Start by locating the existing C-level setlevels() implementation and the surrounding user-facing entry points. Confirm the exposed function handles the stated character and duplicate-level checks, then document its use; done means users can call setlevels() instead of setattr() and understand its validation behavior.

Description

feature request top request

setlevels() appears to exist at C level already but isn't exposed to users.
The advantage of setlevels() rather than users using setattr() is that setlevels() can perform error and warning checks; e.g. that the levels are type character containing no duplicates.
