Amazing what a bracket can do :)
Thanks for the help.

I think it's just the brackets () - plpgsql's parser isn't terribly
sophisticated.
This works for me, but with brackets doesn't.
BEGIN;
CREATE TEMPORARY TABLE test1 (a integer, b text);
INSERT INTO test1 SELECT generate_series(1,100) AS a, 'text for b';
CREATE FUNCTION testdel() RETURNS integer AS $$
DECLARE
n integer;
r RECORD;
BEGIN
n := 0;
FOR r IN DELETE FROM test1 WHERE a % 10 = 1 RETURNING * LOOP
n := n + 1;
END LOOP;
RETURN n;
END;
$$ LANGUAGE plpgsql;
SELECT testdel();
ROLLBACK;
