Thanks for your feedback. > - we don't want to include parsers for other languages, I assume that might mean that no such extensions will be added in the near future. I guess that the scripting interfaces are generally extensible so that other programming languages can be integrated in principle if someone would be keen enough to invest further software development efforts. > and it would further raise the barrier for adding other scripting languages.

I am using this approach around the parameters "--index" and "--max" for a while. I came similar challenges along during the development of my make scripts. I imagine that these SmPL rules can still be executed by the main process while the execution of the other rules will be delegated to subprocesses (or even threads). The scripting environments in the subprocesses would additionally check then which variables accesses should be transformed into data processing requests for the main process.

There are some trade-offs involved. I find it nicer when the Coccinelle software can be directly reused for more use cases.
