Pretty freaky! I never cease to be amazed by this super cool programming 
environment. You are right! What a handy dandy trick. I wonder if that is an 
implementation feature of Squeak or if all Smalltalks exhibit that behavior. 
Anyways, I updated InstanceEncoder on SqueakMap with your caching 
optimization. Thanks for providing explanation of the technique.

Regards,

John
