Very cool Gregory ... when I first heard about Extension methods, I got all excited by the idea! I haven't had the time to dig into it yet, but someone told me that they are a bit slow.

Has anyone had any "real-life" experience using Extention methods who can say whether there's a performance issue with them or not?
