Not cheating at all. After all, think about it...... When learning something we have reference books and look up on line and do research. There is nothing wrong with learning something to use here. I thought it was about learning and using it and trying things out, and not just showing what we already knew? Well, that's how I am using it anyway - use, try, learn, improve.
I reckon as we go on, most of us will pick up more and try more and learn more.
I was not sure if it was quelques quelque sorte. I thought singular since it was of some kind rather than kinds. Anyway, that was my logic.
