*Question:* what is the best way to access a DOTSXP from R's C API in
a function call.

In the future, there may be a C interface for that:

Currently, working with promises most likely requires some non-API
entry points. What's the intended R-side call from the S3 method to
Rust? What's the intended use on the Rust side?

Best regards,
