started to get away from the R function `shared_ptr()`. Not handling all
cases yet, eventually this:
```cpp
template <typename T>
SEXP as_sexp(const std::shared_ptr<T>& ptr) {
return cpp11::external_pointer<std::shared_ptr<T>>(new
std::shared_ptr<T>(ptr));
}
```
will disappear and we'll have individual functions for each as generated by
some macro.
I'm not clear yet about the classes that are currently handled with
`$..dispatch()` methods in R.
