Python defined the semantics of modifying lists while iterating over them, which is better than c/c++ just calling it undefined behavior, but I've basically never seen it not be a bug. Either I end up creating a copy of the list to iterate over, or figure out a way to defer the modifications, or write a new list. Imo the c# /Java behavior of detecting and throwing is probably the best option for non borrow checked languages.
