Any ideas on how to implement this? It doesnt really feel right to wrap the
vector up in a class or struct...

Why would wrapping it in a simple struct not "feel right"? That's how 
vectors are typically implemented in D, judging by posts in these 
newsgroups.
(Hint: you may want to search these groups to see how others have 
implemented vectors & matrices to avoid reinventing the wheel for the 
Nth time)

A struct which only contains one array of floats:
struct Vector {

I may be too finicky but it really seems like codebloat to me. But if there
arent any other solutions...

If it makes you feel any better, that won't change the size or behavior of 
the vector at all.  It'll still be 12 bytes and passed by value.  But the 
nice thing is that you can then add methods to the vector struct.  :\

Thanks! I was just now thinking about that.
