Well, I'd like to learn more and be able to run the python rules
on my system. So if you still have any idea I'd like to listen.
But I don't see any rush on that since for this patch
we can go with the simple repetitive rule that works on default
coccinelle that comes with fedora 28.
In other words, for this patch we are good.
For the future I'd like to learn, but with no pressure or rush!
I really appreciate your support
Thanks a lot,
Rodrigo.
