Variants

Expected [[?x ?y]] but got some other type of binding. Mentat is deliberately more strict than Datomic: we won't try to make sense of non-obvious (and potentially erroneous) bindings.

Expected [[?x ?y]] or [?x ...] but got some other type of binding. Mentat is deliberately more strict than Datomic: we won't try to make sense of non-obvious (and potentially erroneous) bindings.

Expected [?x1 … ?xN] or [[?x1 … ?xN]] but got some other number of bindings. Mentat is deliberately more strict than Datomic: we prefer placeholders to omission.
