Hi Tom,

I have thought a bit more about this issue.  I do agree that,
in particular when specifying ranges, it may not always
desirable to have the formulas automatically adapt when
rows and columns are swapped.

I have just pushed a change that makes $< and @< refer in
a stable way to the first column and row, respectively.
You can also use @<<< to mean the second row and @>>
the second to last row.

I hope this will prove to be useful for such cases.

Regards

P.S. Nick (Dokos), I also added them to get the symmetry with
the @> and $> references :)
