ORA-32035 considered a good thing?

I used to think that it was a good thing that this error was no longer raised in 11.2.
Now I’m not so sure.
SQL> select * from v$version; BANNER ------------------------------------------------------------------------------- Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production PL/SQL Release 11.2.0.3.0 - Production CORE 11.2.0.3.0 Production TNS for Linux: Version 11.2.0.3.0 - Production NLSRTL Version 11.2.0.3.0 - Production SQL> with t as 2 (select 1 col2 from dual) 3 select * from t1; COL1 ----- XXXXX SQL>
Doh!
Note to self: Clear up old Ts, T1s, T2s, etc straight afterwards.
I used to ALWAYS prefix my factored subqueries as subq_*.
This provides a compelling reason to continue that – not that it changes anything of course, just means I’m less likely to make such a typo.

Just to be clear what used to happen:
SQL> with t as 2 (select 1 col2 from dual) 3 select * from t1; select * from t1 * ERROR at line 3: ORA-32035: unreferenced query name defined in WITH clause SQL>
