Point taken, though I like to think of stacks as one of many ways of implementing LIFO behavior.

- brudgers 7y agoI used "stack" to name the LIFO logic sequence not an implementation idiom. Linked list, pointer into sequential memory array, or restaurant plates have a congruent dimension that "stack" abstracts over within the ordinary computing tradition. To me, your observation of the non-composability of stacks seems related to the ability of push-down automata and turing machines to compute more complex inputs than the finite automata (and equivalents). https://en.wikipedia.org/wiki/Automata_theory https://en.wikipedia.org/wiki/Automata_theory
