...because you don't need to do anything special.  Just use the same 
tied data structure you used to put the data into the SimpleList to get 
it out.

In some instances, you'll get a path from a signal handler.  
get_row_data_from_path() converts the path to an index and does 
$slist->{data}[$index] (fetch all columns at row $index) for you.

(er, make that 43rd row, 24th row, and fourth column.  damned 
zero-indexing.  ;-)
