This has the same problem as doctests: it works well for trivial tests 
like the above, but will be difficult to scale towards more complicated 
testing.

unittest-like structuration is really what works best for most testing 
situations, IMO. Alternative testing schemes for "easier" or "more 
intuitive" testing have generally failed as general-purpose tools.
