wow, that was fast as heck! i didn't even have time to explain the changes.

a question: it seems the unittest utility functions were moved back into a seperate version(unittest) block when you implemented #3. was that intentional?

I didn't implement it (note the commit authorship), so I don't know. In general the library should be as light as possible, so if that's comparable to it being inside an #ifdef UNITTEST then I believe that's desirable.
