I'm not sure what you mean by shadowed. But the mechanism by which S-plus
has 'column headers' is to add an attribute called dimnames to the array.
This attribute is a list containing a character vector for each dimension.

It would be very easy to obtain this functionality in python by subclassing
arrays. So you'll probably see this one soon. The only issue is whether we
allow you to use the dimnames for indexing, as in S.
