As long as I'm gravedigging old conversations...! Remember this one,
also from January of this year? Here's a link to the thread in the
c.l.p-d Mailman archive. The first message in the thread is a good
overview of the problem:

Data point: I use -O.¹ Not frequently, not usually, but I have a few

We had a similar thing at Dropbox, where `# coding: pyxl` would enable a
preprocessor that allowed HTML embedded in the Python code. It translated
this to function calls and string literals.
There were however several drawbacks:
- Installing the codec is a bit tricky, and if you don't have it the
How about leveraging the `# coding=` hook that exists
since 2001 to enable the alternative syntax some are advocating for
type hints?

I've seen experiments in the wild using that to support syntax

Naoki's benchmark here is--possibly?--unrealistic.
As mentioned, his benchmark generates a thousand functions, each of
which takes exactly three parameters, and each of those parameters
randomly chooses one of three annota

Not quite, pydantic was released in June 2017 (see HN post:
https://news.ycombinator.com/item?id=14477222) and always used annotations,
PEP 563 was created in Septe
There are a number of issues around recursive types, in general PEP 563
doesn't make a big difference either way in this case.
I think you mean something like
from pydantic import BaseModel
from typing import Optional
class Foo(BaseModel):
x: int
foo: Optional['Foo']
Foo.update_forward_
