Just a quick comment:

As we know, if you override #=, you should also override #hash.  They 
are a pair.

I usually consider #doesNotUnderstand: and #respondsTo: to be a similar 
pair.

It's rather disconcerting for a receiver to actually handle a message 
(even if via a DNU override) when it says it won't.  In such a 
situation, #respondsTo: lies, claiming the receiver won't handle the 
message, when in reality it will.
