Alternative translation method in Python

[ostr00000]

1. In this markdown:
   

   DevelopersHandbook/technical/translation.md

   Lines 109 to 115 in 245f3d3

   	### Python
   	In your Python code, import FreeCAD, then create a function called `translate` with the following code:
   	```python
   	translate = FreeCAD.Qt.translate
   	```

   
   I only see Qt translation by function, but it is possible to translate using tr method from QObject.
   In my opinion, this is a much better option (especially when object-oriented style is used).
   Actually lupdate do not care about parent class, so it should be even possible to implement a custom method:

   class MyGreatClassAlsoExpandingAnotherClassSoItHasALongName:
       def tr(self, text: str) -> str:
           return translate('MyGreatClassAlsoExpandingAnotherClassSoItHasALongName', text)
   	def runTr(self):
   		print(self.tr("My transalted text"))

   Should this translation pattern be encouraged? Or there are reasons why this is not mentioned here?
   (There are problems with subclassing, but I know a workaround for this.)

2. This is a very frustrating error:
   

   DevelopersHandbook/technical/translation.md

   Line 127 in 245f3d3

   print(translate("MyMod", f"This won't {work}")) # NO!

   
   It is so frustrating that I created a flake8 plugin to detect these errors. Can I advertise this flake8 plugin/pre-commit check here?
