My point is that what Peter is proposing is exactly *not* the standard's
feature. We generally avoid using up standard syntax for not-standard
semantics, especially if there's any chance that somebody might come along
and build a more-conformant version later. (Having said that, I had the
impression that what he was proposing wasn't the standard's syntax either,
but just a homegrown CREATE FUNCTION addition. I don't really see the
point of doing it like that when we can do it below the level of SQL.)
