Allowing other functions to terminate a test would be great, but I wonder if it's worth considering changing the "regular" macros to terminate tests through an exception it throws internally, thus avoiding the need to introduce a new set of macros.

You could of course introduce a new macro specifically to throw (and I think that would be a good idea to automatically gather __FILE__ and __LINE__ in a non-messy way), but this way one could just use the regular macros we already know and love in new ways.

It would mean that tests would need to support exceptions unconditionally, but since it's "just" test code, perhaps this isn't that big a problem.
