What's the difference between ssr rewrite's matching algorithm and vanilla Coq's? Interestingly, ssr's `rewrite !`

is linear in the size of the goal when there are no occurrences of the head symbol (and every constant that appears in the goal is either an `Axiom`

or an `Inductive`

), while `autorewrite`

and Coq's `rewrite !`

are quadratic in the size of the goal. (I'll be reporting an issue about this shortly.
