-(* Possible constraints over the instance of a metavariable:
+(* Status of an instance found by unification wrt to the meta it solves:
- a supertype of the meta (e.g. the solution to ?X <= T is a supertype of ?X)
- a subtype of the meta (e.g. the solution to T <= ?X is a supertype of ?X)
- a term that can be eta-expanded n times while still being a solution
