If I'm reading you correctly, then the problem is that in this line you want 
value semantics and are getting references semantics.

One solution would be to make Vector3f a struct and have .position return 
a pointer to it. In D, pointers to structs and structs are almost identical 
from a syntax standpoint (no . vs ->) Then when you want value semantics 
you would use *n.position().
