| Not plenty, but indeed I have the cases. IIRC I have already described
| one example.

designated

functionality,
| each slot has a special meaning.
| Generaly, the container is used from more then entity. For one it is just a
bunch
| of objects that are used in an order, for another entity, each slot have a
different meaning.
| There are even assertions for a specific types, that have be present on a
specific slot.
|
| Slot can be empty of cause. In that case, first entity simply skips it,
second entity
| is also aware of it an acts accordingly.
|
| If I would go your way, I will need a special class for every slot, because
from the
| POV of the second entity, they are all different.
|
| Do you need a code to see this?
yes please.
