Note that the advice to use the representation clause is
only relevant if the type is declared locally,

By the way, we have found it useful to be a little
systematic with these bogus big array types, we call them
Big_ and define them, e.g.

  type Big_Int_Array is array (Natural) of Integer;

Of course you never want to allocate one of these :-)
