Is it intentional that forward references in unittests aren't supported nor detected?

unittest is a function.  It's basically a single function per module that  
is a concatenation of all the unit tests in the module.  Inside functions,  
forward references are not allowed.

You can declare types or include imports using version(unittest) and then  
forward references should work.
