Currently vector_indexing_suite implements a few methods that you would expect from list but not all. It means I have to put this type in my_cpp_modules.pyi:

class vector(Iterable[T], Container[T], Sized):
  # From indexing_suite
  def __len__(self) -> int: ...
  def __setitem__(self, index: int, value: T) -> None: ...
  def __delitem__(self, index: int) -> None: ...
  def __getitem__(self, index: int) -> T: ...
  def __contains__(self, value: T) -> bool: ...
  def __iter__(self) -> int: ...
  # From vector_indexing_suite
  def append(self, v: T) -> None: ...
  def extend(self, v: Any) -> None: ...

Instead of deriving from Iterable[T], Container[T], Sized it would be much better if it were just a MutableSequence[T]. However that needs a few more methods (see the table at the top of this page):

Specifically:

• insert
• reverse
• pop
• remove
• __iadd__

Those methods should be added. It looks like it should be pretty easy.

A similar issue may exist for map_indexing_suite/MutableMapping but I haven't used it yet.
