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.

“Up a lazy river by the old mill run, that lazy, lazy river in the noonday sun.”

“Evaluation is creation: hear it, you creators! Evaluating is itself the most valuable treasure of all that we value. It is only through evaluation that value exists: and without evaluation the nut of existence would be hollow. Hear it, you creators!”
