Thanks!

Since this has been marked as rejected, should we propose alternatives in a new ticket or could we continue discussing here?

Feature #14344: refine at class level
https://bugs.ruby-lang.org/issues/14344#change-76741

* Author: kddeisz (Kevin Deisz)
* Status: Rejected
* Priority: Normal

* Target version: 
----------------------------------------
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?
