Hi :
I would like to create a macro as follows.
Note : the prinln function actually is something more sophisticated,
but I would like to evaluate the composition of one predefined function and
the other from the input argument.
And I got some errors, why?
Thanks
user=> (defmacro asdf [& {:keys [a]}]
`(println ~(comp (partial + 1) a)))
#'user/asdf
user=> (asdf :a (partial * 2))
IllegalArgumentException No matching ctor found for class
clojure.core$comp$fn__
4034 clojure.lang.Reflector.invokeConstructor (Reflector.java:163)
