Being Lazy

Speaker: Peter Marks.

This talk will explore lazy evaluation in Haskell. After a brief introduction to non-strictness, and establishing a basic conceptual model of evaluation in Haskell, the primary focus will be on how we can utilize laziness to allow us to write programs differently to how we would in an eagerly evaluated language. The session will be rich on code with a worked example of a complete program. We'll also touch on some of the pitfalls of laziness that we run into in real world situations.

Peter Marks has been developing software for over thirty years and has been using Haskell commercially for four years. He currently leads the FPF team at Barclays and is an active member of the London Haskell community, running the Hoodlums meetup group.
