Subject: [ruby-core:91442] [Ruby trunk Feature#15374] Proposal: Enable refinements to `#method_missing`

Issue #15374 has been updated by Eregon (Benoit Daloze).


This wouldn't work, e.g. for `hash.first`, or any existing method of `Hash`.

What's a useful case for this feature?

Feature #15374: Proposal: Enable refinements to `#method_missing`

----------------------------------------
Proposal enable refinements to `#method_missing`.
It can be used in the following cases.

```ruby
# Access key value with method
using Module.new {
	refine Hash do
		# name is Symbol or String
		def method_missing(name)
			self[name.to_sym] || self[name.to_s]
		end
	end
}

hash = { name: "homu", "age" => 14 }
pp hash.name
# => "homu"
pp hash.age
# => "age"
```

`method_missing` is hard hacking.
I would like to use Refinements with `method_missing`.
