Indeed, it is a bit surprising. When including `M`, it manages to include `N` (because it's not in the ancestor list because of (1)) and then won't include `M` itself, because of (2).

For the record, (3) is already changed in trunk. I still hope to see (1) and (2) adressed one day.

Bug #8298: Module include inconsistency
https://bugs.ruby-lang.org/issues/8298#change-39049

Author: Student (Nathan Zook)
Status: Rejected
Priority: Normal
Assignee: 
Category: core
Target version: current: 2.1.0
ruby -v: 1.8, 1.9, 2.0
Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN


It has been suggested that I report this as a violation of the object model:

module M ; end
module N ; end
class C ; include M ; end
module M ; include N ; end
c = C.new
c.extend M
d = class << c ; self ; end
d.ancestors
=>[N, C, M, Object, Kernel]

This has been this way for a while...
