so is it a fact that NVL2 can NOT be used in PL/SQL ??? Quite surprised to find.
But was REALLY surprised that I can not find confirmation by googling (yet)

Connected to:
Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bit Production
With the Partitioning, OLAP and Data Mining options

SQL> DECLARE
  2 l_test VARCHAR2(30) := 'hi';
  3 BEGIN
  4 l_test := nvl2('hello','world','earth');   5 END;
  6 /
    l_test := nvl2('hello','world','earth');
