Bug #7261: Symbol#to_proc to retrieve a method from current refinement

• Status: Closed
• Assignee: shugo (Shugo Maeda)
• Target version: 2.0.0
• ruby -v: ruby 2.0.0dev (2012-11-01 trunk 37415) [i486-linux]

[matz (Yukihiro Matsumoto)]

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.
