(** Compatibility layer for [under] and [setoid_rewrite].
This file is intended to be required by [Require Import Setoid].
In particular, we can use the [under] tactic with other relations
than [eq] or [iff], e.g. a [RewriteRelation], by doing:
[Require Import ssreflect. Require Setoid.]
This file's instances have priority 12 > other stdlib instances.
(Note: this file could be skipped when porting [under] to stdlib2.)
