We should strive to avoid warnings at all. Usually (though not always) 
something that is a warning should really be an error.

That said, I think turning these on by default is a very good idea.

I think individual options to turn specific warnings off will complicate 
things too much. What I think we should do is make -wi the default and 
make an option that is just the inverse. I think that will suffice for 
most real use cases (I mean, we're D, not C; we don't have over 9000 
warning variants).
