Andy, If all the types are the same(e.g. all double), then maybe a tuple
is too heavyweight.  I'd think something like vector_c, maybe called 
matrix_c, would be more appropriate.  Or maybe you're wanting units with
that so that the elements would be a double, but a double with units
length/time or something else.  Is that why tuples instead of matrix_c
is being used?
