A `natural' semantics for a form of call-by-need evaluation is

type system.  The paper will soon be available as a Penn technical
report.  Although our semantics is for a linear system (in the -o, !
fragment) and includes reference counting, it does explicitly describe
the pointer manipulations used for the delayed evaluations of
