I think my understanding of OrderedCollections has been incorrect for a very long time. I have never had a situation where it mattered, but in modeling a current project, I think I have been approaching it incorrectly.
Since I have been using Smalltalk, I assumed that a copy of an object is added to an OrderedCollection. A quick test shows that a reference to that object is added to the OrderedCollection.
I just wanted a sanity check on this. Is this true with all collections?
