I don't have those, but I do have a copy of Python 0.9.1 with unmangled

Another advantage of annotating the variable is that it moves some stuff out

Thanks, Paul. I had lost track of Andrew. Good to know he's still out
there. I wonder why his tar file was never sucked up into the
historical releases page.

Seems the original shar is there buried in a Javascript string toward
the end of the file. I think I've got a handle on it, though it will

Was there a date somewhere? I can't recall if this would have been the
first open source release (from just about 30 years ago, sometime in
February 1991) or some time later in the same year?

Use PEP 593 `Annotated` the way Adrian has proposed, but with an additional
parameter which maps the type guard on the given function parameter name:
```python

I certainly wouldn't want to keep `from __future__ import annotations` in
the language forever if Larry's PEP is accepted.
Of course you can still use explicit string literals in annotations.
Your observation about the @dataclass decorator is significant. Thanks for
that.

I've proposed PEP 593 `Annotated` too, but in the typing-sig mailing list:

and Guido had the following answer:

PEP 649 doesn't prevent to use stringified annotations (Larry has previously
mentioned it in its response to Paul Bryan), and they seem to be still required
when `if TYPE_CHECKING:` is used, despite the PEP claim.
And my last message bring some use cases where strings are also required
(notably
If I've understood the PEP correctly, it would cause the following simple
example to fail:
```python
from dataclasses import dataclass
@dataclass
class User:
name: str
friends: list[User]
```
In fact, when the `dataclass` decorator is called, `User` class is not yet
added to the module n
It is an issue if you use `__annotations__` directly and you are using PEP
563's `from __future__ import annotations`. This currently gives some
strings that may or may not refer to existing globals. With Larry's PEP 649
it will raise an error.
