Well you need valid C++ syntax. This isn't really it.

Also, there are dozens of examples in the Rcpp package, on my blog or in the
list archives. You may want to look at those. Many returns multiple items --
just assign to Rcpp::List and go from there. 

And then there are hundreds of unit test example in the (source and binary)
package all of which are also driven by inline.
