Hi guys,

Is there any way to add an element to an empty array (must not use new: anElement)?

Cheers

It sounds like you want to use an OrderedCollection, not an Array. Those will grow and shrink as needed when you use add:/remove: calls.

That being true, there are actually #copyWith: and #copyWithFirst: that will do the trick, although inefficiently.
