[ruby-core:119090] [Ruby master Feature#20715] `Ractor.[]` and `Ractor.[]=` to access Ractor local storage

From: "byroot (Jean Boussier) via ruby-core" <ruby-core@...>
Date: 2024-09-06 19:13:41 UTC
List: ruby-core #119090
Issue #20715 has been updated by byroot (Jean Boussier).


> it would be nice to do the same for Fiber and Thread as well 

Would also be the occasion for `Thread[]` to be actual thread local instead of fiber local. 

----------------------------------------
Feature #20715: `Ractor.[]` and `Ractor.[]=` to access Ractor local storage
https://bugs.ruby-lang.org/issues/20715#change-109678

* Author: ko1 (Koichi Sasada)
* Status: Open
* Assignee: ko1 (Koichi Sasada)
----------------------------------------
Trivial proposal.

Now `Ractor#[]/#[]=` is supported to access current ractor local storage. However, it doesn't allow to access local storage of other ractors.

```ruby
Ractor.current[:foo] = 1

Ractor.new{ 
  p Ractor.main[:foo] #=> nil
}.take
```

So providing `Ractor.[]/[]=` is more reasonable.
Further more, we don't need to use `Ractor#current` and it is slightly faster.
