Lazy Evaluation
Lazy evaluation does not speculate. The incorporation of speculative execution into implementations of the Haskell programming language is a current research topic. Eager Haskell is designed around the idea of speculative execution. Recent versions of GHC support a kind of speculative execution with an abortion mechanism to back out in case of a bad choice called optimistic execution.

Famous quotes containing the words lazy and/or evaluation:

—Michel de Certeau (1925–1986)
“Good critical writing is measured by the perception and evaluation of the subject; bad critical writing by the necessity of maintaining the professional standing of the critic.”
