You seem to be sidestepping some of the points made by the OP, particularly where certain bugs defy conventions laid down in other parts of the language. Garbage-in-garbage-out is fine so long as it's done in a consistent, well-understood way across the language (ie: throwing IllegalArgumentException). It seems to me that instead of being a strategic approach for dealing with such issues in a consistent way across the language (clearly this is not the case), your arguments are just an excuse for not fixing the damn issues (if that's what you're getting at). And that is truly bizarre.
