Description

The original discussion is here https://bugs.ruby-lang.org/issues/14344.

tl;dr

  • Refinements are often used in-place with anonymous modules
  • Having shorter syntax could lower the barrier of entry for Rubyist wanting to explore this feature
  • Previous syntax suggestions were not accepted.

I suggest adding a shorter syntax (technically, API):

# before
using(Module.new do
  refine Array do
    def foo;"bar";end
  end
end)

# after
refining Array do
  def foo; "bar"; end
end

The original idea was to use using_refined instead of refining but after discussing with Matz we decided that it's too verbose, and refining seems better. But is it good enough? Any thoughts?
