I wonder how much does it differ from python's use of C or Cython (I have only superficial R skills). The prototypical example of why Python's C prevents interoperability is how the introspection needed by Jax or Tensorflow (e.g. for automatic GPU usage or automatic differentiation) fails when working on Scipy functions implemented in C.

For instance, I imagine there is an R library that makes it easy to automatically run R code on a GPU. Can that library also work with Rcpp functions?
