Why not use the let* for everything? Or nest a the let*
and let - perhaps overkill... Because I don't see
anything wrong with "independent variables" in let*
(?). As long as there is one data item that is
dependant - otherwise people reading the code will be
confused why the asterisk is there, and start to look
for it...
