New submission from Terry J. Reedy: In msg243635 of the renaming issue #24225, Nick suggested "One path you may want to consider is progressively factoring out a public "idlelib.extensions" API, and treat everything else in idlelib as fair game for renaming. Folks tend to be more tolerant of d

Antony Lee added the comment: Actually, a simpler approach may be the attached patch (pathlib-splitroot.patch), in which case the exception is AttributeError: 'dict' object has no attribute 'lstrip' which is pretty commonly seen when a wrong type is passed to a function. (Note that it is
