Subject: [ruby-core:65482] [ruby-trunk - Feature #9112] Make module lookup more dynamic (Including modules into a module after it has already been included)

Issue #9112 has been updated by Jeremy Kemper.


See #1586

~~~
1. allow multiple inclusion
1. propagate when a module includes a module

Both have been (basically) accepted

Feature #9112: Make module lookup more dynamic (Including modules into a module after it has already been included)

----------------------------------------
If a module (M) is included into a class (C) and afterwards another module (M2) is included into the first module (M) then C does not include M2 and instances do not respond to methods defined in M2. I think instances of C should respond to methods defined in M2 and C should include M2.

I created a gist detailing the problem I have: https://gist.github.com/PragTob/7472643

I think this behavior is confusing, because if I'd reopen module M and just add methods there then instances of C can call those methods. However if I include another module in M then instances of C can not call those methods.

Any opinions on if this would be a better behavior or why it isn't?

(was unsure to file it as a bug or feature)
