Please correct me if I'm wrong, but if we choose the word carefully
(which is why I chose EXCLUDING), I think we're okay? EXCLUDING is
already defined as an "ordinary key word".
Yeah, it's unreserved so it doesn't break use of the same name for
columns or functions. I'm not sure that you can make the syntax work
the way you suggest without bumping up its reserved-ness level.
That's just a gut feeling, I've not tried it ... but the proposed
syntax sure looks a lot like a call to a function named EXCLUDING.
Adding this rule doesn't appear to cause any complications:
target_el: '*' EXCLUDING '(' ')'
I'm not saying we need to do this, although there have been times when I
might have liked it, but I suspect it would not cause us any grammar
problems at least.
