- is_assoc(+Assoc) is semidet
- True if Assoc is an association list. This predicate checks that the structure is valid, elements are in order, and tree is balanced to the extent guaranteed by AVL trees. I.e., branches of each subtree differ in depth by at most 1. Does not validate that keys are sufficiently instantiated to ensure the tree remains valid if a key is further instantiated.
