[ikarus-users] Name for (lambda (x) (lambda (f) (f x)))

[Eduardo Cavazos]

Hello,

Does that have a name in wide use? It can be used it to map over a bunch 
of procedures, calling each with 'x'. I.e.:

(define (arg x)
  (lambda (f)
    (f x)))

(map (arg pi) (list sin cos tan))

Just curious if the idiom has a name. Note that it's also:

    (cut <> x)

A variable arity version as a macro:

(define-syntax args

  (syntax-rules ()

    ( (args x ...)

      (lambda (f)

        (f x ...)) )))

Example:

    > (map (args 1 2 3) (list + - /))
    (6 -4 1/6)
