'MyClass allInstances' will return a collection of all instances of MyClass,
and 'MyClass allInstancesDo:' is the corresponding enumerator.  If you're
just looking for globals, use 'Smalltalk select: [ :instance | instance
class == MyClass]', and substitute 'Undeclared' or a pool name for
Smalltalk to look in the corresponding dictionary.

Something on the order of '(Smalltalk select: [:i|i class == MyClass])
inspect' is most convenient if you have a dictionary inspector.
