Re: [Help-smalltalk] OrderedCollection growing

[Gwenaël Casaccio]

I think it can be helpfull consider the situtation:
  we have enough room but first <= 1 we cannot decrease (if adding item first)
what happen know a new orderedcollection is allocated and items are moved,
in the new behavior the items are just moved ("less" impact on the gc)
