<enumerated> ( seq -- enumerated )

assocs

Class description
An associative structure which wraps a sequence and maps integers to the corresponding elements of the sequence.

Enumerated sequences are mutable; note that deleting a key calls remove-nth!, which results in all subsequent elements being shifted down.
