Have a look at the SVN archive for Rcpp on R-Forge and at Rcpp 0.7.1 which
should be on CRAN "soon" (within days).  You may like what Romain added as
class RObject; there is more coming for environments etc, and external
pointers already got added.

That said, we are trying to maintain the fine balance of keeping the old
interface of Rcpp maintained (as it is being used in a number of places, and
as I feel quite strongly about maintaining published interfaces) yet add a
few 'interesting' things which Romain had been pushing real well for our use
in RProtoBuf and other places.  

There is also a mailing list for Rcpp-dev (with the usual subscribe-to-post)


Three out of two people have difficulties with fractions.
