Heh, yeah, if I had just noticed std.contracts in the first place, I would have realized that I still had __FILE__ and __LINE__ to play around with. Ah well -- D's usual thoughtfulness pulls through again!

And I'm a sucker for bright colors too, so I'm building colorized output into my set of unit test augmentations. :-)
