We do have several classes of errors (fatal, error, warning) so at least some machine-friendly code should be there. Perhaps just follow many protocols out there (http in particular) and separate error codes in groups. Then we can standardize some specific error codes later if we want too but by default, error(), warning() or die() when running in server context will have a fixed error code in each group. -- Duy
