FYI, copy of Guido's message:

I'm planning to accept the following PEPs related to the type system
later this week:

PEP 544: Protocols
PEP 586: Literal Types
PEP 591: Final qualifier and @final decorator
PEP 589: TypedDict

All of these have been proposed for and discussed before.

All of these have been implemented in mypy and (AFAIK) in some other
type checkers (with the exception of Protocols for module objects,
which is in the design stage for mypy but not controversial in any
way).

No substantial opposition came up during the discussions so far. Some
changes were made to some of the PEPs and it seems everyone is happy
with the results.

I expect that these PEPs will be accepted in time to get their
implementations into the stdlib typing.py module in 3.8 beta 1, which
is due May 31st (i.e., in less than two weeks!).

But please follow Guido's request:
