in that case, no - nothing first class that I’m aware of. tho if you were willing to mutate your python environment (e.g.

pip install

into it) - and IIUC how cython works - you could do this today in a two stage pass with a

provides+setup_py

declaration and a pants call to generate a bdist/wheel - and then either a remote or local publish cycle to then consume that wheel as a 3rdparty dep in another target.
