Subject: [ruby-core:68820] [Ruby trunk - Feature #11052] [Open] [PATCH] Blockless Pathname#ascend and #descend return Enumerator

Issue #11052 has been reported by Piotr Szotkowski.

----------------------------------------
Feature #11052: [PATCH] Blockless Pathname#ascend and #descend return Enumerator
https://bugs.ruby-lang.org/issues/11052

* Author: Piotr Szotkowski
* Status: Open
* Priority: Normal

----------------------------------------
It would be beneficial for blockless `Pathname#ascend` and `#descend`
to return an `Enumerator` (rather than raise a `LocalJumpError`).

Example use case of finding the Git root of the current directory:

~~~
git_dir = Pathname.new('.git')
Pathname.pwd.ascend.find { |dir| dir.entries.include?(git_dir) }
~~~
