[Pharo-users] Re: Null Object Pattern

My *concern* with inlining is that since it is designed to short-circuit dynamic method lookup, it is impossible to call a *different* implementation. That is, you lose the opportunity to have the *receiver* decide how to respond to the message. You may think of it as a message, but the caller is deciding how the receiver will respond—which largely defeats the purpose and role of it being a message.

Yes, this is exactly the point I was (apparently badly) trying to convey. Thanks!
