+describes @code{curried}, a variant of @code{lambda} that creates true curried
+procedures which also behave just like ordinary Scheme procedures.  They can
+be applied to their arguments one by one, all at once, or anywhere in between,
+without any novel syntax.  @code{curried} also supports nullary and variadic
+procedures, and procedures created with it have predictable behavior when
+applied to surplus arguments.")
