Sorry, I misread your remark. You're right that at the call site one
needs to remember to add `call/kw` to the front. Ideally (?) it could be
omitted, as it now can in the Schemes that have native keywords. Not
sure how R7RS-large should cope with this. People would have to agree to
add native keyword arguments to the standard; that will not be easy.
