Thanks for the post; I obviously defer to Michael on the final
decision, but I *really* would like a solution that reports an
'argument sweep' as multiple tests, not as one.  They are truly
multiple tests (since they can pass/fail independently), so I think
they should be treated as such.

On the other hand, your code does have nifty features that could be
used as well, so perhaps the best of both can be used in the end.

Cheers,
