That would be a good candidate for a separate package. I am pretty
sure that porters to other Smalltalk dialects (GemStone) are not
really happy about the dependency to the Squeak Package manager.

Also the code is bugged, it only considers the instance-side, use
#classesAndMetaClasses instead of just #classes.
