This library is unstable; compatibility will not be maintained. See Unstable: May Change Without Warning for more information.

package: unstable-list-lib

This module provides tools for higher-order programming and creating functions.

procedure
((conjoin f ...) x ...) → boolean?
f : (-> A ... boolean?)
x : A

Combines calls to each function with and. Equivalent to (and (f x ...) ...)

Examples:

(define f (conjoin exact? integer?))

> (f 1)
#t
> (f 1.0)
#f
> (f 1/2)
#f
> (f 0.5)
#f

procedure
((disjoin f ...) x ...) → boolean?
f : (-> A ... boolean?)
x : A

Combines calls to each function with or. Equivalent to (or (f x ...) ...)

Examples:

(define f (disjoin exact? integer?))

> (f 1)
#t
> (f 1.0)
#t
> (f 1/2)
#t
> (f 0.5)
#f
