Yes, It's mainly because a grouper written on Python. When it will be implemented in C, the difference will be less. This function will be useful beside struct. Note that in my patch for issue17618 struct.Struct("!{}I") is not used.

As for extending Struct, what you think about a more powerful feature? About a method which returns not an iterator, but an iterable and indexable sequence. Here is a sample Python implementation.
