collection, some collections derived from RWCollection return the old instance, others
return nil.

isA() const;

virtual size_t
occurrencesOf(const RWCollectable* t) const = 0;

for a definition of matches.
virtual void
restoreGuts(RWFile&);
Redefined to repeatedly call the global operator
RWFile& operator>>(RWFile&, RWCollectable*&);
followed by insert(RWCollectable*) for each item in the collection.
virtual void
restoreGuts(RWvistream&);
Redefined to repeatedly call the global operator
RWvistream& operator>>(RWvistream&, RWCollectable*&);
followed by insert(RWCollectable*) for each item in the collection.
