Oh, actually I didn't meant that you should use string comparison to test
all ORC filters. It's perfectly OK to use `PredicateLeaf` for leaf predicates,
and only use string comparison to test for `AND`/`OR`/`NOT`. Since there are
not too many cases for the latter, you probably don't need to bother using
those string templates.
The only reason that I suggested using string comparison here is that ORC
doesn't expose necessary interfaces similar to `PredicateLeaf` for composed
predicates. And it should only be used as a workaround rather than a general
rule.
