Bug #11809: method_missing should not be refined

• Status: Closed
• Assignee: shugo (Shugo Maeda)
• Target version: -
• Backport: 2.0.0: DONTNEED, 2.1: DONTNEED, 2.2: DONTNEED

[shugo (Shugo Maeda)]

The following code prints [:Refinement, :abc], but method_missing should not be refined because it's indirect call.

class Foo
end

module Bar
  refine Foo  do
    def method_missing(mid, *args)
      p [:Refinement, mid, *args]
    end
  end
end

using Bar

Foo.new.abc
