In general, removing from a Collection while iterating through it leads to undefined results. The same is true for adding.

That is a question of approach; apart from mentioned #copy I could also do something like

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

col := #(1 2 3 4 5) asOrderedCollection.

[col isNotEmpty] whileTrue: [ col remove: col first ].

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

if I had an Iterator I could also reset it after each change.

What I am asking is what the best approach would be - I want do some processing for each item and remove it from the collection after it is done.
