Bug #15274

Reflection does not report methods defined only in refinements

Description

class C
end

module M
  refine C do
    def foo
      puts "C#foo in M"
    end
  end
end

using M

c = C.new
c.foo # prints "C#foo in M"
c.send :foo
p c.respond_to? :foo
p c.methods.include?(:foo)
p C.instance_methods.include?(:foo)
p((c.method(:foo) rescue false))

__END__
Prints:

C#foo in M
C#foo in M
false
false
false
false

When the refinement M is used I think it would be less surprising if reflection methods (respond_to?, methods, method, instance_methods) report available methods including the ones coming from refinement.
