Issue #12533 has been updated by Artem Khramov.


Hi Tiago, the syntax is

Sorry for offtop.

----------------------------------------
Feature #12533: Refinements: allow modules inclusion, in which the module can call \
internal methods which it defines.  \
https://bugs.ruby-lang.org/issues/12533#change-59422

Right now this isn't possible:

~~~ruby
module Extensions
  def vegetables ; potatoe ; end
  def potatoe ; "potatoe" ; end
end

module Refinary
  refine String do
  # this doesn't work
  include Extensions
  # this would work...
  # def vegetables ; potatoe ; end
  # def potatoe ; "potatoe" ; end
  end
end

using Refinary

puts "tomatoe".vegetables

#=> in <main>': undefined method 'vegetables' for "tomatoe":String
~~~

Wrongly reported as a bug [here](https://bugs.ruby-lang.org/issues/12514). 

According to Shugo Maeda, this was expected behaviour. I argued that this is the way \
most monkey-patches work, and if Refinements can't cover the use case of inserting a \
custom DSL which references itself in the classes it refines, it can't fully replace \
monkey-patches, which I read was the main reason Refinements have been added to the \
language.
