allows the given functions to consume and produce any number of values, as
long as each function produces as many values as the preceding function
consumes, and @racket[compose1] restricts the internal value passing to
a single value. In both cases the input arity of the last function and
the output arity of the first are unrestricted, and become the

a single value. In both cases, the input arity of the last function and
the output arity of the first are unrestricted, and they become the
corresponding arity of the resulting composition (including keyword
arguments for the input side).
