I also spent time trying to find input that would "let \with blocks
destructively change global context defs."  I was surprised that I
couldn't make it happen even after temporarily changing the
Acceptance_set list copies to plain old assignments of SCM values.  My
approach was to instantiate two contexts, with the first context having
a \with ... \denies ... and the next context using the defaults for its
type.  Whether the contexts began sequentially or simultaneously, the
impact of \denies was limited to the first context.  It's strange, but
I'm reluctant to spend more time trying to discover why I can't force a
failure even with code that I'm not actually submitting.
