Just found out that Set >> #swap:with: can be removed too, since 
#fixCollisionsFrom: is implemented in MethodDictionary which was the only 
class in the Set hierarchy that overrode that method. One method less, 
same amount of code, slightly better remove performance. Load 
Kernel-ul.297 first, then Collections-ul.190 from the inbox. Ignore the 
previous versions (Kernel-ul.295 and Collections-ul.188).
