Subject: [ruby-core:106088] [Ruby master Feature#12737] Module#defined_refinements

Issue #12737 has been updated by Eregon (Benoit Daloze).


Ah, so it's to list the refinements (instance of Refinement) under a "namespace module" like `M`, without needing `using`.
I'm unsure of use cases besides debugging, but I think it's useful to add.

----------------------------------------
Feature #12737: Module#defined_refinements
https://bugs.ruby-lang.org/issues/12737#change-94679

* Author: shugo (Shugo Maeda)
* Status: Assigned
* Priority: Normal
----------------------------------------
How about to provide Module#defined_refinements, which returns the refinements defined in the receiver as a Hash, as follows:

```
module M
  refine String do
    $M_String = self
  end

  refine Integer do
    $M_Integer = self
  end
end

p Module.defined_refinements #=> {String => $M_String, Integer => $M_Integer}
```

By `Module#defined_refinements`, you can activate refinements globally:

```
for klass, refinement in Module.defined_refinements
  klass.prepend(refinement)
end
```
