Scheme has rational numbers as a builtin type, so it _is_ possible to pass the
easy-to-type #2/3 as an argument to a music function (AFAIK, this is the only
case where scheme doesn't use polish notation).
Unfortunately, this would not work with \times: #2/3 and #4/6 are the same
rational number, but 2/3 and 4/6 are different tuplet fractions. Also, Scheme
rational numbers may not contain whitespaces, so #2 / 3 is not the same as
#2/3.
(hm.. for obvious mathematical reasons this solution doesn't work, but if it
WOULD have worked, it would have been a nice solution in a mathematical
sense)
