I now think it's best to leave compose,self_compose, and nest agnostic to
the type of f; the user can supply anything callable and we won't attempt
to turn it back into a symbolic function.
Then as a separate issue, symbolic functions can grow an f.self_compose(n)
function that plays nice with types.
