Ah yes, I don't see how I missed that.

I guess "pre-approval" was the wrong word. I meant it as "preliminary" or tentative endorsement, not as "it's already approved".

Feature #11919: Passing a module directly 
https://bugs.ruby-lang.org/issues/11919#change-94406

* Author: sawa (Tsuyoshi Sawada)
* Status: Rejected
* Priority: Normal
----------------------------------------
Refinement requires a named module:

~~~ruby
module MyRefinement
  refine ...
  ...
end

using MyRefinement
~~~

but often (but not always), refinements are called by the `using` command only in once in a single file, and should not need to be named in such case. Also, the purpose of refinement is to not pollute classes with methods. Necessity to define a module and polluting the name space looks to me to go against this idea.

I would like to do:

~~~ruby
using Module.new do
  refine ...
  ...
end
~~~
