I understand the `-> theading macro in Clojure applies all the provided functions provided to a given argument. However, it doesn't seem to work with anonymous functions. For example:
user> (-> 4 inc inc dec) 5
But:
user> (-> 4 #(+ % 1) #(- % 1) #(+ % 1))
Returns the error:
clojure.lang.Symbol cannot be cast to clojure.lang.IPersistentVector [Thrown class java.lang.ClassCastException]
If someone knows a way around it would be helpful. Thanks!
You can have anonymous functions in Clojure macros. You are having problems, because you are missing some parentheses. :) Your example is edited below.
(-> 4 (#(+ % 1)) (#(- % 1)) (#(+ % 1)))
