In lazy evaluation, a suspension (or in Henderson's terminology, a "recipe") is a closure with a flag indicating whether the expression has been evaluated or not. When the expression is evaluated the first time, this flag is set. Subsequent requests for the value of the expression will not attempt to re-evaluate it.
