Hi Thomas,
These changes work. However, if in fancy.core I try to :refer to the function
I am interested in, the behaviour reverts always using the runtime. That is,
if I change the ns in fancy.core to:
(ns fancy.core
(:require
;;[fancy.fancy :as fancy]
[fancy.fancy :refer [fun]]
)
)
Is this behaviour a necessary artefact of clojurescript macros, or just an
oversight in the code? If it's necessary, can you tell my why?
