[New-bugs-announce] [issue37922] inspect.getsource returns wrong class definition when multiple class definitions share the same name (but are defined in different scopes)

[Leonard Truong]

New submission from Leonard Truong <leonard at truong.io>:

Here's a case where `inspect.getsource` returns the wrong class definition when a file contains multiple class definitions with the same name. This pattern is valid runtime behavior when the class definitions are inside different scopes (e.g. a factory pattern where classes are defined and returned inside a function).

```
import inspect


def foo0():
    class Foo:
        x = 4
    return Foo


def foo1():
    class Foo:
        x = 5
    return Foo


print(inspect.getsource(foo1()))

print(foo1().x)
print(foo0().x)
```

Running this file produces
```
❯ python inspect-getsource-issue.py
    class Foo:
        x = 4

5
4
```
