No. The ALL keyword has to follow the operator it applies to --- the
syntax is not just "all(something)" but "something op all(something)".
I don't think we can relax that without creating syntactic ambiguity.
If you want to work with non-commutative operators such as regex, you
may need to invent your own operator.
