Language.Hakaru.Evaluation.Lazy
Description
Lazy partial evaluation.
BUG: completely gave up on structure sharing. Need to add that
back in. cf., gvidal-lopstr07lncs.pdf for an approach much
like my old one.

evaluate :: forall abt m p. (ABT Term abt, EvaluationMonad abt m p) => MeasureEvaluator abt m -> TermEvaluator abt m Source #
Lazy partial evaluation with some given "perform" and
"evaluateCase" functions. N.B., if p ~ 'Pure then the
"perform" function will never be called.
