type t = (term, term) Var.Subst.t

val empty : t
val mem : t -> term Var.t -> bool
val add : t -> term Var.t -> term -> t: Add new binding to substitution Fails if the variable is bound already

val find : t -> term Var.t -> term option

raises Not_found: if the variable is not present

val eval : t -> term -> term
val eval_nonrec : t -> term -> term: Evaluate under substitution, but consider the substitution as not idempotent
