Hi,
I want to make method chains like this:
----
#lang racket
(define (pipe init . procs)
(foldl (lambda (x y) (x y)) init procs))
(pipe '(3 4)
(lambda (l) (map sqr l))
(lambda (l) (apply + l))
sqrt)
5
----
In racket libraries, rackjure module looks usable.
But, rackjure's threading(~>) denys lambda.
----
#lang rackjure
> (#fn(map sqr %) '(1 2))
'(1 4)
> (~> '(1 2) #fn(map sqr %))
[Error] lambda: not an identifier, identifier with default, or keyword in: (1 2)
> (define (sqrlst lst) (map sqr lst))
> (~> '(1 2) sqrlst)
'(1 4)
----
In this case, what is the suitable solution?
Thank you for reading.
Taro
