What is the best way to pass Clojure vectors and maps to JavaScript
functions?

Currently when I need to call a JavaScript function that takes an
array I do something like

    (js/my_js_fn (.array (vector 1 2 3)))

and I pass Clojure maps like

    (js/my_js_fn (.strobj (hash-map "a" 1 "b" 2)))

This feels a bit gross, since I'm digging into the implementation
details.

Is there a recommended way to do this yet?
Some kind of reader macro (say @@) would be okay, turning

    (js/my_js_fn @@(vector 1 2 3))

into

    (js/my_js_fn (.array (vector 1 2 3)))

at read time.

Ideally though, the compiler would automatically convert ClojureScript
objects into JavaScript native objects when they're passed to a
function in the js/ namespace.
