This book was released on 2016-09-20 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to solve a long-standing problem with list fusion, a new compiler transformation, "Call Arity" is developed and implemented in the Haskell compiler GHC. It is formally proven to not degrade program performance; the proof is machine-checked using the interactive theorem prover Isabelle. To that end, a formalization of Launchbury's Natural Semantics for Lazy Evaluation is modelled in Isabelle, including a correctness and adequacy proof.
