--- Comment #11 from Jonathan Wakely <redi at gcc dot gnu.org> --- I disagree. Once it's documented, people will rely on it and scream if it changes. Caveats about something maybe changing in future don't help. If it's documented to behave one way today, people will depend on that. It seems you already know what the behaviour is today, so how would documenting it but saying "this might change tomorrow!" help you? It tells you nothign you don't already know.
