Thomas Mueller commented on OAK-225:
------------------------------------
Let me rephrase it: I'm not convinced it's worth to support such queries *right
now* (in the near term). If there are many such queries, then yes, if it's the
only one, I would rather postpone support until the end of the year, and make
such queries throw an exception currently.
