:: (a -> Bool) -> ([a] -> Bool) package:numhask

any :: Foldable t => (a -> Bool) -> t a -> Bool
numhask NumHask.Prelude NumHask.Prelude
Determines whether any element of the structure satisfies the predicate.

Examples

Basic usage: 
>>> any (> 3) []
False

>>> any (> 3) [1,2]
False

>>> any (> 3) [1,2,3,4,5]
True

>>> any (> 3) [1..]
True

>>> any (> 3) [0, -1..]
* Hangs forever *
all :: Foldable t => (a -> Bool) -> t a -> Bool
numhask NumHask.Prelude NumHask.Prelude
Determines whether all elements of the structure satisfy the predicate.

Examples

Basic usage: 
>>> all (> 3) []
True

>>> all (> 3) [1,2]
False

>>> all (> 3) [1,2,3,4,5]
False

>>> all (> 3) [1..]
False

>>> all (> 3) [4..]
* Hangs forever *
