Thinking about it again, it seems to be enough to disallow the bare
use of an atom in subsequent arguments of the `->' macro. In other
words, all subsequent arguments have to look like function calls (or
macro uses).

It doesn't change much. The baking procedure would be as simple:

(-> bowl
    (add flour)
    (add sugar)
    (add eggs)
    (mix)
    (pour)
    (bake (celsius 450)))
