------------------------------------------------------------------------

I assume it is something that belongs in rpy2 itself (or an extension of it), 
and not pyarrow? 
(as long as we consider {{_export_to_c}} public, the POC 
(https://github.com/rpy2/rpy2-arrow/blob/main/rpy2_arrow/sexpextptr.py) is only 
using public APIs, and it seems no additional APIs are needed on the pyarrow 
side to make this possible)

> Per discussion on the mailing list, we should see what is required (if 
> anything) to be able to pass data structures using the C interface between 
> Python and R from the perspective of the Python user using rpy2. rpy2 is sort 
> of the Python version of reticulate. Unit tests will then validate that it's 
> working
