All good points. But I know that part of the reason it's a no-go is
consistency. "in" has to scan the keys, not the values, or it would be
inconsistent with AAs.

Personally I wouldn't mind dropping "in" in favor of two new infix
functions "contains" and "containsKey", which would disambiguate the
two cases (and give extra functionality for AAs). But it's probably
too late to change things now, so forget I said anything. :-)
