Description

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?
