Vladimir Sitnikov commented on CALCITE-2327:
--------------------------------------------
{quote}I disagree with "off the track" {quote}
Do you still disagree?
{quote}but even if I was: why didn't you communicated at least that?{quote}
1) I consider issue/PR to be abandoned since the latest messages/commits were
in July
2) I see no reason to spend time on communication for such trivial changes.
What kind of communication did you expect?
Did you expect I would ask you to put unrelevant changes to the PR?
Did you expect I would ask you to keep optimization and fix it for nullable
case?
> In 3 valued logic mode (b and not b) may not be simplified to false
