I tried around a bit and couldn't get it to work either. Also tried to find an explanation for the issue on the web, but didn't really get that far either. Sometimes, Python import behavior remains a mystery :D

I searched too, there is literally nothing about that in the web, at least I couldn't find it. Tried with AI too but I didn't got lucky :[

I did what you suggested and moved the filters module to tg/ext/filters.py and removed the underscore from the handler names in tg/ext/_handlers. Also, I noticed that some imports were still not working, so I fixed that with the help of pytest.

Since we are here, are these merge checks supposed to be succesful? Did I messed something up for that to not be working? At least the required ones seems to be fine.
