  Just to clarify the very confused statement above: This problem has
to do with keypaths, not predicates. I muddled my statement because I
was thinking about the fact that some predicate tokens are disallowed
depending on the store type. I'm pretty sure @distinctUnionOfSets and
other operators are supported on all store types, but I'm not sure.
