The 'yrruc' function appends the argument lists in the opposite order
(although it does not reverse the order of the individual arguments in
each list).

For instance:
((curry list 1 2) 3 4) = (list 1 2 3 4)
((yrruc list 1 2) 3 4) = (list 3 4 1 2)

I plan to add PLT 4.0.1-compatible, keyword-supporting versions of
these functions to cce/scheme.plt version 1.2 (as yet unreleased) by
the names curry1 and curry1r.  The new scheme/function library
(provided by default in #lang scheme) provides curry and curryr, which
have a similar purpose but different behavior.
