The function would still have a "return type" explicitly given when
it's declared so that wouldn't be non-Adaish.  The explicitness I was
talking about was this

type some_record 
   is record
      the_word : word;
      remaining : some_string;
   end record;

function get_word (text : in some_string) 
   return some_record;

rather than

function get_word (text : in some_string)
   return (word, some_string);


it could be defined like this:

function get_word (text : in some_string)
   return (word, some_string) is
begin
   -- do somethis with the string, 
   -- finding w and str.

   return (w, str);
end get_word;

and used something like this:

...
(a, b) := get_word (temp);
...

It was curiosity, not an attempt to make things easier to "hack".
