I see. I understand that racket's threading macros are NOT SIMPLE IMPLEMENTATIONS. Racket's threading macros can reduce lambda object creations.
#lang racket (require threading) (define (add2 x) (+ x 2)) (~> 1 add2) ; ok (~> 1 ((lambda (x) (+ x 2)) _)) ; ng -> ok (~> 1 ((curry + 2) _)) ; ng -> ok (define adder% (class object% (super-new) (init-field x) (define/public (incr) (lambda (y) (+ x y))))) (define adder (new adder% [x 2])) (send adder incr) ; ok (~> 1 ((send adder incr) _)) ; ng -> ok -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
