Yes, it is the same. Everything is passed by "reference" (*). And if you copy the collection you'll get two collections referencing the same object. E.g. | a c1 c2 | a := Object new. b := OrderedCollection with: a. b identityIncludes: a. "true" c := b copy. c identityIncludes: a. "true" (*) Some objects like SmallIntegers are "immediate" objects, and could be considered that they're passed by value. E.g. 1 copy == 1 "true" Regards, Esteban A.

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?
Thanks!
