Miniml.InfvInstval empty : tNo bound sort variables
val generate : UVars.AbstractContext.t -> t list2^n possible instances for this context
val default : UVars.AbstractContext.t -> tAll sorts informative
val ground : UVars.Instance.t -> tFrom a ground instance returns an informativity instance
val instantiate : UVars.AbstractContext.t -> t -> UVars.Instance.tThe other way around
val encode : t -> string optionA string that can be used as an identifier suffix, guaranteed to be injective for instances of the same length.
