As said: calling set_defaults in the constructor cannot
possibly stay in the spec: that breaks in those cases where
set_defaults would throw.  If the c'tor then throws for a
given type, you can't create any context of that type _at_
_all_.

Hmm, you mean the ones we have in the errata I assume?  Yes,
some of them are bigger.  However, they are there to fix
errors.  Any item in particular you are unhappy with?

I'll commit the latest state of the errata file to CVS in a
minute...

Hmm, would you mind if we discuss that on the phone?  I
agree that we are running in circles somehow, but I would
like to get the discussion to a conclusion one way or the
other, instead of leaving it open...  Can I call you
somewhere?

Thanks, Andre.
