While I was working on defuting your point, I recognized that with subclassing the driver the code duplication can be removed easily for debug drivers. IMO, debug drivers need to provide the full range of options for testing purposes anyway. That still leaves the following issue <http://www.antlr.org:8888/browse/ANTLR-265>. Any ideas how to solve this?

Probably. I have to wait for 3.2 before I could introduce LINQ anyway. Maybe the situation is different then.

Even LINQ to Objects?
