This will work starting with 2.064:

It will print stuff twice though because I didn't suppress 
native unittest runner. Didn't actually dwell deep into runtime 
hooks so don't know what is best way to do it (maybe we need 
one more enhancement for it)

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...)
