Wording in `mypy.plugin.Plugin.get_method[_signature]_hook` docstring

Documentation

The docstring of these plugin hook methods currently say:

https://github.com/python/mypy/blob/057508b4cb405fbc22e26b44f764b142352fcce5/mypy/plugin.py#L647-L648

...

https://github.com/python/mypy/blob/057508b4cb405fbc22e26b44f764b142352fcce5/mypy/plugin.py#L664

I understand this to mean that the argument to fullname will be "__main__.Base.method", because __main__.Base defines method.

However, this doesn't seem to be the case. Setting up the same example in the docstring:

• mypy.ini

  [mypy]
  plugins = plugin.py
  files = test.py
  

• plugin.py

  from mypy.plugin import Plugin
  
  def plugin(version):
      return TestPlugin
  
  class TestPlugin(Plugin):
      def get_method_signature_hook(self, fullname):
          if fullname.startswith("test."):
              print(f"Hook will be called with `{fullname}`")
  

• test.py

  from typing import Any
  
  class Base:
      def method(self, arg: Any) -> Any: ...
  
  class Derived(Base): ...
  
  var: Derived
  var.method(42)
  

$ mypy
Hook will be called with `test.Derived.method`

I installed as far back as mypy 0.9x and it was the same behaviour as described above, displaying test.Derived.method (not test.Base.method).

Is there something wrong with the docstring (perhaps from outdated behaviour that no longer applies), or have I misunderstood something?

Comienza con los docstrings de los hooks enlazados en mypy/plugin.py alrededor de las líneas 647-648 y 664, y después reproduce el ejemplo proporcionado de mypy.ini, plugin.py y test.py. Compara el fullname documentado con el valor observado test.Derived.method; el trabajo estará terminado cuando el docstring explique correctamente el argumento del hook o aclare el malentendido señalado.
