"Squeak works up the hierarchy until an asString method is encountered.
If the method is not encountered, then Squeak will return an
doesNotUnderstand error."
Is that really so? Does it traverse up the hierarchy instead of using
some
sort of lookup table? Wouldn't that be a performance concern for deep
hierarchies? Is this standard Smalltalk behavior or is this just how
Squeak
does it?
Thanks!
