While we're on Dynarray, why did we create our own Invalid_arg exception, 
and not use the standard Invalid_argument exception?  Why especially did 
we override the default invalid_arg argument?  I'd much rather do string 
concatenation instead:

if (idx < 0) || (idx > d.len) then
        Pervasives.invalid_arg ("Dynarray.delete: invalid idx " ^
                                (string_of_int idx));
...
