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:
“Take us generally as a people, we are neither lazy nor idle; and considering how little we have to excite or stimulate us, I am almost astonished that there are so many industrious and ambitious ones to be found; although I acknowledge, with extreme sorrow, that there are some who never were and never will be serviceable to society. And have you not a similar class among yourselves?”
—Maria Stewart (1803–1879)
“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.”
—Raymond Chandler (1888–1959)
