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

Author: matz (Yukihiro M.)
Status: Open
Priority: Normal
Assignee: shugo (Shugo M.)
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.
