Bug #14671: Refining Module#refine itself introduces strange state
https://bugs.ruby-lang.org/issues/14671

* Author: shyouhei (Shyouhei Urabe)
* Status: Open
* Priority: Normal
* Assignee: 
* Target version: 
* ruby -v: ruby 2.6.0dev (2018-04-09 trunk 63122) [x86_64-darwin15]
* Backport: 2.3: UNKNOWN, 2.4: UNKNOWN, 2.5: UNKNOWN
----------------------------------------
```ruby
using Module.new {
  refine Module do
    def refine *;
      puts self
    end
    public :refine
  end
}
Object.refine # => NoMethodError
```

It is possible to refine Module#refine, but there seems to be no way to call it.
