On the elementsEqual problem, or “[Pitch] Set and Dictionary should not be Sequences”

From the other thread:

Presumably that order would be fixed (because there is no advantage in having it somehow be random for any implementation of any collection I’ve ever heard of), so you can easily define all the things you save for Collection on it (first, last, indexing, etc).

This would imply for me that you can't easily define first, last, indexing. etc for a random collection. Is this a misinterpretation or your true opinion? (there's no merit in writing a long statement if the fixed order isn't actually important for your opinion ;-)
