I'm guessing all it means is that you don't need to provide that feature in 
order to create a D compiler. As Lutger said, if your compiler doesn't have that 
feature, you can use an external tool that has it. In fact, I think that's how 
this feature got implemented in the first place, but I'm not 100% sure.
