Keith,

And there will be more. Maybe it will take people still a while to realize
that the problem is the current mindset, that posits a decidability that
simply cannot coexist with completness.  You need to choose -- which
one do you want to have? You cannot have both from the same system.

And, yes, of course I'd expect meaningful error messages to provide
an automatic solution as much as possible, and as much as I desire.
