GH-112361: Speed up pathlib by removing some temporary objects. by barneygale · Pull Request #112362 · python/cpython

Construct only one new list object (using `list.copy()`) when creating a
new path object with a modified tail. This slightly speeds up
`with_name()`, `with_suffix()`, `_make_child_relpath()` (used in walking
and globbing), and `glob()`.
