That's the preferred approach for me too, but it doesn't work for
functions that take a variable number of arguments.
Konrad.
Personally, I prefer to use multple "prototypes":
(defn bla
([aaa bbb ccc] )
([bbb cc] (bla 0 bbb cc)))
etc.

There's clojure
Hmmm... if we take a look at the first arglist...
[name doc-string? attr-map? [params*] body]

attr-map? clojure.lang.IPeristentMap
params* - IPeristentVector
body - IPerisistentSeq

Occasionally I have to write a custom def macro, and this would make
life easier. I would have to use it to provide specific feedback, but
it seems like an idea worth pursuing.

In Clojure it is idiomatic to have optional args at the front of the
signature. This makes it easy to define convenient caller APIs, but it
leads to bulky let forms like this one (from clojure.core/defmulti)
(let [docstring (if (string? (first options))
(first optio
