Well, the spec has
<quantified comparison predicate> ::=
<row value expression> <comp op> <quantifier>
<table subquery>
<quantifier> ::= <all> | <some>
<all> ::= ALL
<some> ::= SOME | ANY
and not the reverse. The array syntax is an abuse of this notation
and doesn't have the reverse either. I'm not really sure how much
new code would be needed to support the other case, or whether it
would be worth the trouble.
