Any chance of getting a TODO added that would provide the option of having the optimizer pick join order when you're using the ANSI join syntax? IMHO I think it's bad that using the ANSI syntax forces join order; it would be much better to come up with a custom syntax for this like everyone else does. But I'm sure people won't want to change the existing behavior, so special syntax to do the opposite is almost as good. -- Jim C.
