This is great. I love the unittest blocks and UDAs. This way I 
can still have very easy-entry (as in "just write unittest {}") 
unittests while gaining the power of unittest frameworks.

It's a hell of a lot better than having some class with 
attributes containing methods with attributes, containing 
parameters with attributes :) I'm developing RSI when writing 
tests in other languages. (In Java I develop RSI just declaring 
variables...)
