And return the error code in an out parameter instead? Great idea. So readable. So much in the spirit of Pascal.

Any more such suggestions on how to write code? Where can one download "Florian's Style Guide" - so one will not do that mistake again?

Sorry for the sarcasm, but that pattern worked in the past and there's absolutely no reason it shouldn't. Come on, guys, that's really schizophrenic: On one hand such changes break compatibility in a BIG way and on the other hand there's whining about adding a new keyword, because it could break compatibility in a couple of rare cases.
