Description

Hello,
I've been trying to use WeakArrays. This is the error when I issue WeakArray new:

Object: nil error: did not understand #do:
MessageNotUnderstood(Exception)>>signal
UndefinedObject(Object)>>doesNotUnderstand: #do:
WeakArray>>do:
WeakArray(Array)>>printOn:
WeakArray(Object)>>printString
WeakArray(Object)>>printNl

Doesn't happen with WeakArray new: size.
