This means you need to construct Triangles at run time, in Game constructor, not at compile time in this initialization syntax.
Got it. But are reference-types "computable" at compile time at all? Shouldn't they be relying on D runtime?
To my understanding Triangle instantiation happens when Game constructor is called. I assume that D runtime has been initialized already, and thus there should be a valid GC and it should be fine to instantiate a reference-type.
As well, if I'm wrong about Game constructor, then compiler generated errors are wrong and misleading. The compiler should be swearing at `Triangle player = new Triangle;`, or not?
