I see, thanks for the explanation about unittests being a special 
case of functions. That is really helpful context and makes sense 
since functions should evaluate sequentially. A little surprised 
the same restrictions apply to a static struct declared inside of 
the unittest, but that is easy to work around by moving the 
declarations to the version section.

cheers,
