[New-bugs-announce] [issue43746] Weird typing annotation closure behavior

[conchylicultor]

New submission from conchylicultor <etiennefg.pot at gmail.com>:

I observe some strange closure behavior for typing annotations when the name is defined

```
x: x = 1  # Works, __annotation__ == {'x': 1}
```

This creates issue, for example:

```
from ... import losses

class A:
  # AttributeError: 'Losses' object has no attribute 'Losses'
  losses: losses.Losses = losses.Losses()
```
