Description

Later. Allows for testing of functions that depend on the order of evaluation.

TODO: move this functionality to the testing package for Unamb.

Synopsis
isAssocTimes :: (EqProp a, Arbitrary a, Show a) => Double -> (a -> a -> a) -> Property
isCommutTimes :: (EqProp b, Arbitrary a, Show a) => Double -> (a -> a -> b) -> Property
delay :: RealFrac t => t -> a -> a
delayForever :: a
Documentation
isAssocTimes :: (EqProp a, Arbitrary a, Show a) => Double -> (a -> a -> a) -> PropertySource
Is the given function associative when restricted to the same value but possibly different times?
isCommutTimes :: (EqProp b, Arbitrary a, Show a) => Double -> (a -> a -> b) -> PropertySource
Is the given function commutative when restricted to the same value but possibly different times?
delay :: RealFrac t => t -> a -> aSource
Delay a value's availability by the given duration in seconds. Note that the delay happens only on the first evaluation.
delayForever :: aSource

A value that is never available. Rerun of hang from unamb, but replicated to avoid mutual dependency.

TODO: Remove when this module is moved into the unamb-test package.
