The main reasons none of the result objects support it are because
none of testtools' users (vast horde that they are) have asked for it.
and because it's a crummy interface. TextTestRunner ought to at some
point in the future call stopTestRun() instead of printErrors() and
let the result object drive its own reporting.
However, in the mean time, perhaps the best workaround is to write an
adapter. I'd definitely be open to accepting such a thing as a patch.
I'd even be open to writing it, but don't hold your breath, unless you
know some wicked breath-holding tricks I don't know about.
