In Racket we actually have a threading macro with ~>
This:
(- (bytes-ref (string->bytes/utf-8 (symbol->string 'abc)) 1) 2)
Becomes this:
(~> 'abc
symbol->string
string->bytes/utf-8
(bytes-ref 1)
(- 2))

- peatmoss 9y agoI believe the use of "~>" rather than "->" in Racket was set in #lang rackjure which adds in some of the Clojure syntax to Racket. Also amusing is their explanation: > For example the threading macros are ~> and ~>> (using ~ instead of -) because Racket already uses -> for contracts. Plus as Danny Yoo pointed out to me, ~ is more "thready". http://docs.racket-lang.org/rackjure/index.html#%28part._.Background_philosophy%29 http://docs.racket-lang.org/rackjure/index.html#%28part._.Ba... More thready indeed :-p
