Hello everyone,
I like to introduce you to cljs-devmode, which is a development mode for
ClojureScript. It is really a primitive prototype for a ClojureScript
development mode, but it works for me so far. I only wrote it to get started
with ClojureScript in one of my Clojure web applications.
Thanks Max. This is wonderful. I can throw my current hack-job out the
window.

PS. Should I encounter any issues, I'll post them via github.

Hi!

problems.

This would be a straightforward solution:
(defmacro when-lets [bindings body]
`(let ~bindings
(when (and ~@(map first (partition 2 2 bindings)))

It works well in simple cases, but breaks e.g. in case of parameter
destructuring.
If you read `(source when-let)`, you'll see

This is an odd one. It seems that, when new functions are added to
