Yes, I was now using python3.10, which has this new nice features for type hints. I discovered later that it was indeed a feature of python3.10. Would you prefer that I remove this or are you going to update to python3.10 anyways?

[AlessandroLovo]

The new syntax appeared in only 2 instances, so I simply got rid of it
