super_method fails on some UnboundMethods
Description
super_method fails to go up the ancestry chain for methods that are only defined in included modules:
module A
def foo
end
end
module B
def foo
end
end
class C
include A
include B
end
class D
def foo
end
include A
include B
end
C.instance_method(:foo) # => #<UnboundMethod: C(B)#foo> (ok)
C.instance_method(:foo).super_method # => nil (wrong, should be <UnboundMethod: <something>(A)#foo>)
C.new.method(:foo).super_method # => #<Method: Object(A)#foo> (ok)
D.instance_method(:foo).super_method # => #<UnboundMethod: Object(B)#foo> (ok)
D.instance_method(:foo).super_method.super_method # => #<UnboundMethod: Object(A)#foo> (ok)
Note that the results for C and D's super_method differ slightly, with one outputing "C(B)" and the other "Object(B)". I don't understand why "Object" shows anywhere in my example. I would have expected the output to be "D(B)" in the later case. Should I open a different issue for this?
