When an object that is to be referenced by SqueakProxy is initialized, it
attempts to register its relevant methods' parameter-lists with
SqueakProxy, which keeps a list of unique references to each class's
methods' parameter-list(s). After that, every time an instance of a given
class evokes SqueakProxy, it is automatically assigned a reference to the
correct parameter-list(s) and SqueakProxy keeps track of what is what when
passing parameters around.

Reference counting is done by SqueakProxy, and when the count hits zero,
the parameter-list(s) are deleted.
