list-sorted? < lisprocedure
vector-sorted? < v #!optional start endprocedure

These procedures return true iff their input list or vector is in sorted order, as determined by <. Specifically, they return #f iff there is an adjacent pair … X Y … in the input list or vector such that Y < X in the sense of <. The optional start and end range arguments restrict vector-sorted? to examining the indicated subvector.

These procedures are equivalent to the SRFI 95 sorted? procedure when applied to lists or vectors respectively, except that they do not accept a key procedure.
