An interesting case is failing to compile illegal code that was compiled
before, this of course is a bug fix, and no one could say otherwise, yet
for users of the compiler it is often a (perhaps serious) regression. We
have found that in some cases, the discombobulation of such a "fix" is
sufficiently great that we make it a warning for one release, or put in
a debug flag to allow the old behavior.
Otherwise a general note is that I find myself in 100% agreement with
Mark Mitchell's position on this issue.
