Hi list,
is there a specific reason Stack is extending from LinkedList, instead of
using a LinkedList internally?
To me, it seems that the protocol that LinkedList, SequenceableCollection,

Any thoughts on this?
Originally it used encapsulation,
when where?
In Pharo 1.0 (and Squeak of course).

but for some reason it was changed to use inheritance, probably for a "cleaner"
system. IMHO the changes should be reverted.
I was not aware that Stack was a subclass of linkedList, it looks again
subclassing versus subtyping. And subtyping is better.
