This assumes a mode of debugging after the stack is unwound, instead of
debugging before throwing the exception.  In the latter case, not only
do you have the possibility to restart, you don't need to reify anything
to have access to a backtrace.

I don't think this is the sort of thing that a Scheme report should
standardize.
