Hi Christopher,

If I understand your descriptions correctly, your proposed changes are
very cool.

Could you elaborate a little bit on performance?

* Are we going to see speedups?  In what cases?  How much?

* If we lose performance, could you quantify that a bit with some examples?

A question regarding backwards compatibility (I might have missed that
in the description, sorry):  Are you converting existing queries on the
fly each time, or do we have to convert our queries once?  If yes, is
there some assisting code?

Thanks,
Martin
