Very exciting.

There was some conversation about splitting off these feature requests
into a separate package (RcppExtras?) on list a while back -- obvious
candidates include sample(), the list of R functions that might be
improved in Rcpp (as per Hadley et al's comments), and perhaps this...

I haven't seen any discussion on this in a while.  Is this something
that warrants discussion, or something to keep in mind for later?
I'd prefer such a package to depend on RcppArmadillo so that my
implementation of sample() can be easily included.  Are there
downsides to this?

thanks,
Christian
