I think this is way too heavy weight of a process ... =[ It seems to slow
I filed the bug specifically complaining about clang-format's changes (such
as the revisions you cite) and none have argued for clang-format's current
behavior. I know bugs aren't great points of discussion, but unless a bunch
of people show up on this thread saying that they strongly prefer the other
formatting, why not just fix polly and move on? I want to use, dogfood, and
provide feedback on the new behavior, and I can't if we just revert the
change because we're still pondering deeply the really marginal style
