Some wierd Module#append_features behavior

[Brian Mitchell]

I couldn't quite figure this out... I am either missing something (I
hope) or there is a small bug:

Module === Module #=> true
Module === Module.new #=> true

af = Module.instance_methodappend_features)

af.bind(Module.new).call(Module) # ok
af.bind(Module.new).call(Module.new) # ok
af.bind(Module).call(Module) # ok
af.bind(Module).call(Module.new) # error!

TypeError: wrong argument type Class (expected Module)

I am kind of puzzled by this... any ideas?

Brian.

To be more specific, the third "ok" is unexpected if the fourth is not
going to work (which went as I expected).

append_feature tried to append features in Module to a module from
Module.new, but Module itself is a class, not module.

Yes. I know that part. The odd thing that I should have been more clear on is:

af.bind(Module).call(Module).

Module is a Class is both cases but this one seems to work. I am not sure why.

It is a bug. Thank you for finding it.
