Nice edits.
I'm unclear on the meaning of the last line in detail #3, "(Loop
variables may also use constructs like x[i] or x.a; this form may be
deprecated.)"
Does this mean that "(x.a for x in mylist)" will initiatly be valid but
will someday break? If so, I can't imagine why. Or does in mean that
the induction variable can be in that form, "(x for x.a in mylist)".
Surely, this would never be allowed.

Will do.
