Unit testing Distilled
I'm of the opinion that a testing framework should not test itself.
Doing so would be incredibly dangerous, and give me little to no useful output. I would never know if my tests were passing because the library was correct, or if they were passing because Distilled was broken and not reporting errors correctly.
That puts me in extremely unfortunate position of having to load up a separate testing framework, even though avoiding those libraries is really what I wanted to do in the first place. I'm guessing I'll end up using Mocha, that's probably the most flexible for right now.
