Should we use a constant or provide an explanation for the "magic constant"?

having i and capital I is a bit confusing. I would call this one currInterval and i -> index

Yeah I know, names are not the best! But I'd like to keep it as it is to match ANTLR 4.

IntervalSetseems to be a hot path, so the less nullability checks we have, and the less iterators we use, the better.Also tested with the ANTLR 5 test suite.
