Hmm, does Hive support using dot notation to access fields that are
arbitrarily nested in arrays? If not I think it would be better to just
support one level. Also, the code added for that feature uses a lot of mutable
state and is a little hard to follow (in addition to removing the type check).
Since I'd really like to include your parser fixes and test cleanup, what
do you think about breaking out the GetField on arrays change into another PR?
