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.
"If process indicates if it is worth removing the item" processed:= col select: [ :each | col process: each ]. col removeAll: processed. It is an interesting dicussion actually :-) Phil
