Looks cool but it seems like it might still need some work?

I tried it on one of my Django `admin.py` files and it created NameErrors.

    class TestAdmin(admin.ModelAdmin):
      list_filter = ("foo_method",)

      def foo_method(self, obj):
        return "something"

      foo_method.short_description = "Foo method"

    # It turned it into this:

    class TestAdmin(admin.ModelAdmin):
      list_filter = ("foo_method",)

      # NameError
      foo_method.short_description = "Foo method"

      def foo_method(self, obj):
        return "something"
