Abstract: In his seminal paper "Natural Semantics for Lazy Evaluation", John Launchbury proves his semantics correct with respect to a denotational semantics, and outlines an adequacy proof. We have formalized both semantics and machine-checked the correctness proof, clarifying some details. Furthermore, we provide a new and more direct adequacy proof that does not require intermediate operational semantics.
Change history: [2014-05-24]: Added the proof of adequacy, as well as simplified and improved the existing proofs. Adjusted abstract accordingly. [2015-03-16]: Booleans and if-then-else added to syntax and semantics, making this entry suitable to be used by the entry "Call_Arity".
