Yes, Oskar made a good point in his post.  The main issue I was 
concerned with was the vector literal syntax.  Currently array literals 
are allocated on the heap when you declare them, which would be 
prohibitively costly in most situations.  In order for low-dimension 
vectors to be useful, they need a simple constructor syntax that does 
not allocate anything on the heap.
