If the dependencies are templated, like large portions of Phobos, 
then no, they and their unit tests will be compiled together with 
your code.

When you import a module, the compiler adds its unit tests to the 
list of all unit tests that need to be run. At the moment the 
compiler can't know if you're importing your own module (that you 
want to test) or a third-party one (that you don't care about its 
unit tests).
