I might easily be mistaken, I can't really believe this was overlooked for so long, but: Is it possible that there is no getter for the range of a SELECT query? I.e., when you do $query->range(0, 10), there's no way (apart from reflection or other dark magic) to retrieve that again?
If this is indeed the case, and I'm not just blind, this seems to me a pretty big oversight, even though it's quite obviously not an important one.
