Hello,
Currently when you have a reflection warning in a -> form, you have to
split it:
clojure.core=> (-> "hello world" (.split " ") second (.split "o") seq)
Reflection warning, line: 1269 - call to split can't be resolved.
("w" "rld")
I propose to modify the -> macro to make it preserve type hints, hence
you could write:
clojure.core=> (-> "hello world" (.split " ") #^String second (.split
"o") seq)
("w" "rld")
Here is the patched macro:
(defmacro ->
"Threads the expr through the forms. Inserts x as the
second item in the first form, making a list of it if it is not a
list already. If there are more forms, inserts the first form as the
second item in second form, etc."
([x] x)
([x form] (with-meta
(if (seq? form)
`(~(first form) ~x ~@(next form))
(list form x)) (meta form)))
([x form & more] `(-> (-> ~x ~form) ~...@more)))
