Yes, indeed, it is a normal Array and that cought my attention. But since I
have no idea about Weak stuff...I also noticed that WeakOrderedCollection is
declared as:
OrderedCollection subclass: #WeakOrderedCollection
instanceVariableNames: ''
classVariableNames: ''
poolDictionaries: ''
category: 'Collections-Weak'
instead of using the #*weak*Subclass: ... message:
OrderedCollection *weak*Subclass: #WeakOrderedCollection
instanceVariableNames: ''
classVariableNames: ''
poolDictionaries: ''
category: 'Collections-Weak'

Do you know a weak collection that is not broken in Pharo and let me do a
addLast: ?

Thanks. I will check how many there are and try to fix them.
