How so?  Backward compatible with what?  DCOracle doesn't 
try (or even want;) to be backward compatible with oracledb.
We were only striving for compatability with the DB-API.
The DB-API documentation seems pretty liberal on this to me.
(Actually, it is too liberal, IMO.  I think it should 
specify a database-independent syntax.)

You could write a preprocessor to scan the SQL for :1 and transform it
to something like :p1.  We may do this eventually.
