Thanks for the insights! > Let's say that your code creates a complex object tree from some configuration settings, and executes Python methods and code from all over it, using heavy OO. Luckily, this does not apply to the codebases I'm working on, which are all quite functional (no classes, no inheritance, pure functions exclusively, immutable data types, etc.) I have the feeling that this will not strike me that hard. If you rely on pure functions you have all the application state that you need for the function on the parameters and you pass all new state back through `return`. I guess all I had to do is convert the types once for the C function call (from Python to C) and once for the `return` (from C to Python)?
