I've added a new rule to flake8-bugbear.

In brief, the rule detects bugs like the following:

some_list = [1,2,3]
for i in some_list:
  if i % 2 == 0:
    some_list.remove(i)
  print(i)

(More context at github.com/PyCQA/flake8-bugbear/issues/445)

I'd be happy to contribute if its desired to implement this rule in ruff as well 🙂
