[ruby-core:84780] [Ruby trunk Feature#14344] refine at class level

Issue #14344 has been updated by Eregon (Benoit Daloze).


The whole purpose of the Module around it is so multiple refinements can be bundled up together in a Module and that Module is passed to #using.

I don't think #refine should enable refinements after the block.
It doesn't seem clear to me and is too confusing with the existing usage of #refine.
Whether #refine is called on a Module or not would have very different semantics.

Also I guess in general refinements are not defined right in the class using them, especially if they are not trivial one-liner methods.

Feature #14344: refine at class level

----------------------------------------
I rely on refinements a lot, but don't want to keep writing `Module.new` in code. I'm proposing `Object::refine`, which would create an anonymous module behind the scenes with equivalent functionality. So:

~~~ ruby
class Test
  using Module.new {
    refine String do
      def refined?
        true
      end
    end
  }
end
~~~

would become

~~~ ruby
class Test
  refine String do
    def refined?
      true
    end
  end
end
~~~

It's a small change, but reads a lot more clearly. Thoughts?
