[Rcpp-devel] about the RcppSexp (Rcpp::RObject) constructors

Now that I am on the road for class inheritance and all that, I am not
sure anymore that the myriad of constructors for Rcpp::RObject are a
good idea, i.e since we have for example :
Rcpp::RObject( double& d ) ;
it is then valid (as far as my -- still learning -- understanding of C++
goes) to do this :
Rcpp::Environment( 1.3 )
which of course is a nuisance.
I was thinking of replacing the constructors with a set of functions
(and C++ polymorphism makes it easy I think), so we would have a
function (let's decide about its name first) for example wrap and many
overloaded with different parameters.
Rcpp::wrap( const double& d)
Rcpp::wrap( const std::vector<int>& d)
then the wrap can dispatch to the appropriate class.
