Hi Everyone,

Thank you for the detailed suggestions. Now that I have a better idea of what CSA is, I also think that this check could be better implemented in clang-static-analyzer. Being able to reduce the number of false positives using path sensitive analysis is in my opinion the most important advantage of using CSA.

What do you think? Should I close this PR, and open a new one when I'm ready with the CSA checker?

By the way, I don't have any users. This check is more like a University project I picked. The reason I started with clang-tidy is simply because that was the suggestion my teacher gave me.
