    Description

      A user may wish to use some functionality available only in pyarrow using reticulate; it would be useful to be able to construct an R wrapper object to the C++ object inside the corresponding Python type, e.g. pyarrow.Table.

      This probably will require some new functions to return the memory address of the shared_ptr/unique_ptr inside the Cython types so that a function on the R side can copy the smart pointer and create the corresponding R wrapper type
