Off the top of my head, there is also Kawa[0].

I'm afraid that I don't quite follow. Do you mean a CL-style declare[1]
within the body of the function; or do you mean that there may exist
type declarations elsewhere that modify the function's type signature,
and whose possible existence is implied?

Let's keep in mind that it's not only function parameters and return
values that may benefit from type declarations; as with CL-style declare
statements, it could be useful to pepper other symbols with type
