Hi,
I've been using method_missing overly much in my code lately, and it's prompted me to think a lot about it's limitations.
<snip/>
So, any thoughts?
I'm wondering in which situation you need this. Although I understand the benefits of your approach I don't see the use case for this.
I think I see what Mark was getting at. As I understand it, if I defined a proxy object that used method_missing to forward all method calls to an underlying object, I could call
proxy.to_ary
and if the underlying object was an Array, this would work.
However, if I passed that into a library that was using duck-typing, and that lib did
proxy.responds_to? :to_ary
the answer would be false. So, my Array proxy doesn't look as much like an Array as it needs to.
Do I understand correctly?
Cheers, Sam
