Extra brownie points for you for using Doxygen markup in RcppXPtr.h -- awesome. For symmetry, shall we split off 'code' (ie function bodies) into RcppXPtr.cpp? No string views but I like the headers short and just as interface descriptions. [ Can you tell that the first language thrown at me in Karlsruhe was the then-very-fresh-and-new Modula2 ? ;-) ] Dirk
