I think you are correct.
So you may have to make do with just setting a default value in the existing
constructor's body, and offering an additional setter.
Rcpp modules are a sort-of half-way house between the full glory of C++ and
the more direct interactive nature of R. Not everything can be mapped that
way, and we point to class member functions by name only.
