|Hi

|This works, thank you!

|But it has to be just "initialize" instead of "conn.initialize" - otherwise
|ruby complaing about calling an private function unsing an expicit receiver.

Oops, I forgot that initialize was private method.

  conn.__send__(:initialize, *args)

or

  conn.instance_eval{initialize(*args)}

would do.  Just "initialize" would invoke the method of the
DbConnection class.
