PEP 572: Explain why 'as TARGET' is inferior ( #711 )
...
Also (perhaps superfluously) explain what's wrong with `->`.

PEP 572: Move the proposed evaluation order change to "Syntax and semantics" ( #710 )

PEP 572: Address several small issues ( #709 )
...
- Dropped "TODO: Include Guido's evidence, and do a more systematic search."
I think the current text is good enough.
- Relented on assignment expressions in default values other than top
level. (Mainly because the syntactic/semantic check would be
awkward, and it was already called out as a possible style
recommendation instead.)
- Clarified that a lambda counts as "the current scope" (containing an
assignment expression).
- Added prohibition on [... for i in i := ...].
- Specified that scope-related prohibitions should raise
TargetScopeError, a subclass of SyntaxError.

PEP 572: get rid of side-by-side tables; drop unnecessary TODO ( #708 )
...
Alas, the side-by-side tables caused horribly misindented code.

Pep 572 update ( #654 )
...
- Remove changes to comprehension scope
- Make := in comprehensions assign to containing non-comprehension scope
- Clarify binding precedence (tighter than comma, not at same level as =)
- Remove mention of more complex targets in the future
- Explicitly disallow toplevel :=
- Rewrite section on differences with =, enumerating all of them
- Remove "here's how this could be written without :=" from examples
- Tweak first paragraph of "Syntax and semantics"
- Add "Exception cases" (various explicit prohibitions)
- Clarify that lambda is a containing scope
- Clarify that := and = just don't mix
- Added "Open questions" section
- Added two new rejected alternatives: "Allowing commas to the right"
and "Always requiring parentheses"
- Minor edits
* Start a section on real code
* Correct/clarify "commas to the right" section
* Add Tim and Guido as authors
* Update abstract to mention :=
* Rule out targets conflicting with comprehension loop control
* Add timcode.txt as Appendix A
* Add os.fork() example
* Add TODOs about evaluation order
