Something like this combined with some IDE smarts to offer up the possibilities for `fun` after I type `(-> a` ... that could be very cool.

You mentioned autocompletion a few times and that is something available via LSPs (janet specifically has one that has this) or through the editor (e.g. emacs can use swank for common lisp). It's no different for any other language integration.
