Thanks. That works, but it's really ugly.

  I don't understand why a slice of a multi_array(_ref) isn't simply a 
multi_array_ref. The current implementation seems to make dealing with 
slices unnecessarily complicated. The documentation on views is also 
very thin. Can anyone explain the rationale behind the design?

Thanks again,
