Terrific!  I can confirm that works for me and, in a way, a work-around
is better than a fix.  With the work-around, I can distribute the
package without needing to require that people get some not-yet-release
version of R that fixes the problem.  I do hope the problem gets fixed
though :)

By the way, I  couldn't see how the perl code excerpted earlier paid any
attention to {}.  But perl is not my native tongue.
