That may very well be bad practice (I certainly wouldn't advise writing code 
like that), but it's also not definitively wrong. Unless it's definitely a bug, 
I think that the compiler should keep quiet about it, because anything that it 
yells about has to be treated as a bug, and we shouldn't be forcing people to 
change their code just because there _might_ be a bug in it.
