foreach(i,ref val; ndim_arr)??

[Jay Norwood via Digitalmars-d-learn]

I noticed some discussion of Cartesian indexes in Julia, where 
the index is a tuple, along with some discussion of optimizing 
the index created for cache efficiency.  I could find foreach(ref 
val, m.byElement()), but didn't find an example that returned a 
tuple index.   Is that supported?
