*nod* I understand. My concern is that this adds friction to users doing error checking-makes it easier to reach for an API that not only doesn't encourage it (the original API) but doesn't allow it - meaning the author has to choose between a more convenient API, and maybe doing error checking - this seems like it'd discourage error checking, which would be unfortunate.
