Minor bug: erroneous "Value assigned to ... never used in ..." hint

[Claus Pedersen]

I have the following code:

CREATE OR REPLACE FUNCTION tester (param IN NUMBER)
RETURN BOOLEAN IS
  test VARCHAR2(1);
  ret  BOOLEAN;
BEGIN
  IF param = 1 THEN
    ret := TRUE;
  ELSE
    test := CASE param WHEN 2 THEN 'Y' ELSE 'N' END;
    ret := (test = 'N');
  END IF;
  RETURN ret;
END tester;

Compilation of this code gives:
7 Hint: Value assigned to 'ret' never used in 'tester'

This is not correct. If line with the CASE construct is removed, the function is correctly compiled with no hints. Can this be fixed?

That is indeed not correct. We'll fix it.
