This looks great for trivial code, but what about more complex code?

    destructuring-bind([a b &rest c] some-list lambda([x] +(a b x)))

or

    loop(for i from 1 to 10 collect 1+(i))

or

    with-current-buffer(get-buffer-create("foo")
      save-excursion(
        insert(text)
        buffer-substring-no-properties(point-min() point-max())))

This looks horrible. There is an advantage in using the same syntax for both lists and function application.
