[snip] I didn't say there were. If we had adopted REALLYREALLYDISTINCT, we *would have had* to update the test cases. Thus, with the DISTINCT, there were test case that *might have had* to have been updated. I.e., the mere risk of having to change test cases shouldn't block progress, IMHO, or affect how we discuss things. Just as it hasn't in the past. In any case, I believe that the examples of problems with the algebra can be stated against ground data, wherein LC1 and LC2 coincide. So, why should this be a blocker? Is this meta-debate useful? How about some commentary on the problems with the semantics of conjunction in the algebra? After all, it's not like this point is *new*, and it clearly must be addressed. Cheers, Bijan.
