I should say, we have absolutely no performance requirements, at least in terms of what this will do. If we could add 10% developer efficiency for 20% performance hit, we'd take that in a heartbeat. The nanoseconds this construct might cost are just irrelevant to us, our customers, or our bottomline. Obviously if you're writing some low-level performance sensitive code then this won't be free, but I expect most people are in our situation.
