Bug #7261: Symbol#to_proc to retrieve a method from current refinement
https://bugs.ruby-lang.org/issues/7261

Author: matz (Yukihiro Matsumoto)
Status: Open
Priority: Normal
Assignee: shugo (Shugo Maeda)
Category: core
Target version: 2.0.0
ruby -v: ruby 2.0.0dev (2012-11-01 trunk 37415) [i486-linux]


Currently Symbol#to_proc retrieves the global definition of the method, since refinement is a lexical scope.
But if possible, it is better that Symbol#to_proc can retrieve a method from current refinement.

  module Silly
    refine Integer do
      def bar; p :bar; end
    end
  end

  module Stupid
    using Silly
    1.bar # => :bar
    [1,2].each(&:bar) # => undefined method `bar'
  end

What do you think?

It should be done before 2.0.0 if we merge, to avoid future compatibility issues.

Matz.
