The section on Automatic Variables is silent on ordering of lists; is it
safe to assume they will preserve the original order, and can that be
addressed in the doc?
For instance the patch below adds "in the order originally specified" for
$?; there would need to be similar verbiage of $^ et al. Alternatively
maybe this could be addressed with an extra sentence in the intro where it
says "Here is a table of automatic variables:".
