It's a golfing reference :) It means "what you would expect".

Is it true that later versions use interfaces and earlier versions
don't? If so, then I think it is fine.=20

I prefer to think of the drivers as flabby :) I think they should write
their APIs to interfaces.

But it would require some FAQ entries. Like:

Q - Why can't I cast the Connection to an OracleConnection?

A - You need to upgrade to version 8.x.y or later.

Or if we felt like being a bit more general:

Q - Why can't I cast the Connection to an XyzConnection?

A - Proxool's Connection only implements public interfaces provided by
the driver. If XyzConnection isn't an interface then you can't cast it.
