Hi all,+
Could those in the know comment on how this<...> proposal is (or is not) consistent with the fundamental Smalltalk principles that:
1. "an object is send a message and responds with an object" 2. there is no other "magic" in the system.
Are we proposing a break fromv this ? If so, IMO we need to really get it right before we commit.
Thanks
Brent

Take 15 mins to read the code dealing with Pragma preferences, and you'd have your answer. The short answer is no, they just provide a different way of dynamically deciding what message you want to send. The closest equivalent would be the logic used to decide which ImageReadWriter subclass to actually use. Cheers, Henry
