On a (possibly) related note:
The #js data literal doesn't seem to work correctly
inside the go macro as well: Compiling
(go (prn (<! (go (let [bar "bar"] #js {:foo bar})))))
produces
"WARNING: Use of undeclared Var <ns>/bar ..."
and prints out
"#js {:foo nil}"
if <ns>/bar is nil.
Of course,
(go (prn (<! (go (let [bar "bar"] (js-obj "foo" bar))))))
works as expected.
