I've seen this claimed, but I have never seen any actual numbers. What speeds up? By how much? is it actually measurable? Maybe they've marched past me in this thread-from-hell. But I can't recall having seen any (not now, not before). That said, I think the more serious issue is that if Luto complains about the capability-capturing code being completely broken, then people need to take that *seriously*.
