DMD throws compile error:

Is this expected behavior? It tripped me while trying to use 
DerelictVulkan :(

I think the problem comes from the way you compile and link your 
code. I you compile both modules together like this it should 
work out:

dmd -ofresult main.d stuff.d

(I'm on the phone, so I can't verify if it works atm)

If that's the solution, some people may find a relatively less known dmd

Yeah, -i has been a super-convenient thing to use.  For unittesting
individual modules, etc., I can just `dmd -i -unittest -main -run
module.d` and it Just Works(tm). It's awesome.  Highly recommended.
