* Status: Assigned
* Priority: Normal
* Assignee: nobu (Nobuyoshi Nakada)

* ruby -v: ruby 2.4.1p111 (2017-03-22 revision 58053) [x86_64-linux]

~~~ruby
using Module.new {
refine Enumerable do
alias :orig_sum :sum
end
}
module Enumerable
def sum(*args)
orig_sum(*args)
end
end
class GenericEnumerable
include Enumerable
def each
end
end
# GenericEnumerable.new.sum # if we uncomment this line, `GenericEnumerable#sum` will work
Enumerable.prepend(Module.new) # if we comment out this line, `GenericEnumerable#sum` will work
p GenericEnumerable.new.sum # undefined method `orig_sum' for #<GenericEnumerable:0x0000000127c120 @values=[1, 2, 3]> (NoMethodError)
~~~
Is this intentional?
