I'm fairly sure I'm not doing anything at all with multiple
inheritance. This is a single instance of single inheritance.
I will peruse the list; what I had seen in my searches so far had
suggested no conclusive answer.

Rcpp itself is open to mulitple inheritance.
Rcpp modules, which your question appears to be concerned with, currently
cannot as discussed a few times on this list. You find perusing the list
archives informative.
