My options seem rather limited, I need to make a Pipeline from (Smalltalk -> C -> Python) then go back (Smalltalk <- C <- Python). Since Smalltalk does not support Python directly I have to settle with the C/Python API (https://docs.python.org/3.6/extending/embedding.html#beyond-very-high-level-embedding-an-overview). Any suggestions?
