Does that have a name in wide use? It can be used it to map over a

Just curious if the idiom has a name.
It appears to be called "Thrush"[*] (a.k.a. the Cardinal Idiot):
(define I (lambda (x) x))
(define C (lambda (x) (lambda (y) (lambda (z) ((x z) y)))))
(map ((C I) pi) (list sin cos tan))
It doesn't sound common though.
