Good catch.

Also, iterating through the elements and using operator() to assign 
elements is going to be slow because the reference count for the NDArray 
object will be checked each time.  Chances are you should be getting a 
pointer to the data and using some kind of read function that reads the 
file all at once (after the dimensions are discovered and used to 
allocate the array).
