My point is not to single out Vlad here! I don't think this patch
author is any worse or better than the next one. There are other
examples enough, e.g. VRP is from other contributors and it has had a
few horrible pieces of code from the start that just don't get
addressed, or var-tracking for which cleaning up a few serious compile
time problems will be a Big Job for stage3. It's the general pattern
that worries me.
Ciao!
