Re: Common interval literals (was comments on the comments...)



Dima, Vincent, John, and all,

In my opinion, we want the strongest standard we are capable of preparing.  We should revise and resubmit.  I do not think there is anything especially controversial being added at the last minute; just careful attention to some details.

I say, “Revise, please.”  

And THANK YOU to the few doing the WORK.  I very much appreciate your efforts.
