Should we warn if we detect null derefernces or void value uses ?

Warnings cause problems in that they fracture the language into different, 
confusing dialects. Let's say you've joined a new group, and you're expected to 
maintain some D codebase you are totally unfamiliar with. It compiles with 
warnings. Is that a problem or not?

Every warning in the compiler is a problem with the language specification, not 
a solution.
