[ruby-core:100668] [Ruby master Feature#17294] Feature: Allow method chaining with Pathname#mkpath Pathname#rmtree

[get.codetriage]

Issue #17294 has been reported by schneems (Richard Schneeman).

----------------------------------------
Feature #17294: Feature: Allow method chaining with Pathname#mkpath Pathname#rmtree
https://bugs.ruby-lang.org/issues/17294

* Author: schneems (Richard Schneeman)
* Status: Open
* Priority: Normal
----------------------------------------

Currently in my code when I want to create a pathname object and create a path at the same time I must use tap

```
path = Pathname.new("/tmp/new").tap(&:mkpath)
```

I think it would be cleaner to be able to chain on the results of these methods instead:

```
path = Pathname.new("/tmp/new").mkpath
```

This is a change in return value but after research on github I do not believe many (if any) are relying on the current behavior to return nil https://github.com/search?l=&p=1&q=.mkpath+language%3ARuby&ref=advsearch&type=Code.

Here is my diff:

[ruby-core:100676] [Ruby master Feature#17294] Feature: Allow method chaining with Pathname#mkpath Pathname#rmtree

[brooke]

Issue #17294 has been updated by bkuhlmann (Brooke Kuhlmann).


I would like this too. I've been using [Refinements](https://www.alchemists.io/projects/refinements/#_pathname) to improve Pathname behavior but this would be better.
