A:
No, it's more like multiple inheritance, but not completely the same. Modules can be used to mix-in functionality, so you don't have to rewrite the same code for multiple classes. Composition is where objects hold references to other objects.

I may be getting my design pattern terminology mixed up, but have you looked at def_delegator and def_delegators from Ruby's standard library forwardable?
