Hi Sylvain, Sorry for the late answer, I just moved from Europython, to a week full of meetings to holidays (almost) off the grid.
I didn't follow pylint progress but 2 years ago clonedigger was the clear winner. But you're right I need to see if having this other tool is worth pursuing. I'll test again, in one or two weeks to see how they compare now. It's only a single data point but it is a beginning L.
