Run `dub clean; dub test -v` and you'll see that main.d isn't compiled 
into the test library.

dub test substitutes its own main() function over yours. In order to do 
this, it needs to not compile in your main() and to compile in its own. 
dmd doesn't have an option to replace main(), so dub drops that entire 
source file.
