If you really want to hunt for unused syntax and we wind up needing a (.)
analogue then (->) is currently a reserved operator, so opening it up for
use at the term level could be made to work, and there is a precedent with
c/c++ pointer dereferencing.
Imagine this possible code:

    foo :: Maybe Foo -> Bar
    foo (fromMaybe def -> x) = \x -> case x of
        Foo x -> x->y->z

I think it might get a bit ugly to give it a 5th meaning.
