Ah nice. I had mainly opened that issue as a reminder for myself not as a call to action ;)

What would be nice to check as well would be the constructors from frames, or from multiple collections via the static from methods. However, they clash with the from keyword from python. That was the main reason for me to not directly go to solve this ;) Would probably need some from_event and from_collections overloads on the c++ side to make things available on the python side in a working manner.
