I agree and that is not my requirement. I only need to know when order
changes (if Benoit changes the implementation). Example if I remove one
item, does the enumeration order of rest change? If not, I have no problems.

I choose to use collection, because I have long list of objects and mostly
I need to access them individually and fast. If I would use array I would
have to enumerate them to find the object I wanted to access. Or constantly
update index table when object is removed.
