Only compile time metadata is possible for ClojureScript vars now. And that's
perfectly fine.
What would be cool is to be able to add arbitrary keys to it. That'd still be
immutable metadata only added at compile time. Unfortunately, it's ignored now:
ClojureScript:cljs.user>
(defn expect-string
"Throws AssError for non-strings!"
{:expectation true}
[x]
(assert (string? x)))
#<function expect_string(x){
// ... generated JS
}>
ClojureScript:cljs.user> (meta #'expect-string)
{:arglists ([x]), :test nil, :name expect-string, :column 1, :line 3, :file
"<cljs repl>", :doc "Throws AssError for non-strings!", :ns cljs.user}
;; :expectation key is lost
What do you think?
