(*
 * A special "custom" value that prohibits Pervasives.compare,
 * but allows marshalling. By temporarily adding this value as a
 * _first_ field in a * data structure that is not supposed to be
 * compared using Pervasives.compare, one can weed out all the
 * inappropriate usages of Pervasives.compare, (=), (<), etc.
