This doesn't quite address one assumed detail -- should the official
test suite be modified to use as few (and as simple) Test.pm features as
possible, so that Test.pm can then be made even simpler?  This would
likely make the test suite slightly clumsier in places, while making it
easier for a new implementation to get enough functionality in place so
that Test.pm is fully supported.

If the test suite is modified as above, then there pretty much HAVE to
be additional Test modules -- people programming third-party code would
go insane using only the anemic Test.pm that would be sufficient for a
simplified test suite.

Of course, that doesn't mean that a more extensive Test module can't be
standardized, or even an official version written that all perl6's can
ship with.  It doesn't have to be all-encompassing, but a core set of
"best practices" test tools, perhaps just taken from Perl 5 experience
of the TDD folks and modified for Perl 6 differences, would be nice to
rely on everywhere.
