In a test S/S I have a 2x2 named range. From the documentation of get_named_range I expected it to return a 2 element tuple, each element itself a 2 element tuple of cells. What I received was a 4 element tuple of cells.
Having looked at the code I thing there is an error. At the end of the method it has
for row in rows: result.extend(row)
I believe "extend" should be replaced by "append".
