I agree, I'm all for compiler warnings like these - they are rather 
useful to find stupid mistakes, which I certainly make from time to time.

The only problem is if it becomes tedious (e.g. involves lots of of 
typing or extra code) to tell the compiler that it found a false 
positive, or if it finds lots of stuff that isn't really wrong.
