Right. Maybe it's the traditional Lisp read that's the main factor here because it seems that you could expand in place without issue given even arbitrary expressions.

If a.b expands to (a b) then (f v w).(g x y) would just expand to ((f x y) (g x y)). At first glance, that definitely appears to be a cool way to grab just one of the results from a function return (ala (f x y).2).

Hmm, on the down side, you could have statements like (or worse):

    (bst-find tree 45 f<).(if (< 10 42) (/ 4 3)
                              (> 4 2)   x
That being said, having to change read to get this to work may affect far too much and make arc too ugly.
