I tried that very thing and was surprised that it worked.  The reason I was 
surprised was because I would have expected sequence-item to have answered 
the tuple object itself, rather than just the "value" component.  It would 
seem that sequence-item should always answer the item itself, and there 
should be two special variables, sequence-key and sequence-value which 
answer the key and value respectively if the sequence-item happens to be a 
tuple or mapping.

Anyway, thanks for the info.
