What if it's instantiated in another module? Right now I'm having 
issues where if I run 'dmd a.d b.d -unittest' and the class 
template in b.d is instantiated in a.d and it compiles and the 
tests inside my class template run as they should, but when using 
'dub test' the tests in my class template don't run at all as if 
it isn't instantiated in a.d even though it is. This is the 
original issue that I had that prompted me to create this thread.
