oh I see now what you mean, thanks. Yes, Hive does the same. We may have to
revisit completely our parsing of literals but since it is a breaking change I
am not sure it will be possible before 3.0. And if the next release is going to
be 2.5, probably this means that we have to wait before doing anything like
that.
