I think warnings being part of the compiler is a mistake. I don't 
think they will ever be removed, so I think this is a good 
compromise.

The only reason compilers have warnings in them is because C++ 
needs an entire compiler to warn you about potential problems, 
and it has since become tradition for that feature to be 
included. We can just as easily rely on dscanner for this kind of 
thing and simplify the compiler.
