It was new behavior in the sense that Numeric didn't support
multidimensional array takes and puts at the time. For a long time it
was the only kind of array indexing IDL supported (1-d and implicit
.flat of multidimensional arrays). Speaking only for myself, I found
the .flat semantics more often as unwanted behavior than convenient.
I'd rather keep the numarray behavior in this case and make the .flat
case explicit (but I understand the difficulty of that approach). There
is the possibility of a custom index option (but ugly I suppose)
where flatten is a special object that indexing recognizes as signaling
a different interpretation to indexing.
