Description

The standard library has a tactic simp_to_model for proving facts about TreeMaps. We prove some facts about TreeMaps in HeapInstances.lean, but we do not make use of this automation yet. To make these proofs more robust, we should figure out how.

Research direction

Read the TreeMap proofs in HeapInstances.lean and inspect the standard library's simp_to_model tactic to determine where it applies. The work is done when the relevant TreeMap facts use this automation and the proofs remain valid.
