Where exactly is documented the extern(D) x86-64 calling 
convention? Because currently seems like a mess according to 
the dissasembly. First X parameters on stack from left to 
right, last 4 in registers. But wait, if you have less than 4 
parameters, they are passed in register. Again, WTF?

Reading this, I'm experiencing true fear for the first time in my 
life.
