		SimonSapinUnsubmitted Not Done Reply This description isn’t factually wrong, but wouldn’t it be a serious bug if the on-disk format ends up varying across different platforms? SimonSapin: This description isn’t factually wrong, but wouldn’t it be a serious bug if the on-disk format…
		SimonSapinUnsubmitted Not Done Reply Correction: since `index_format` starts with `>`, it opts in both to big-endian and to "stardard sizes" so `index_size` is in fact platform-independent. See docs in https://docs.python.org/3/library/struct.html#format-characters Maybe `>` should be added to the format string for `big_int_size` and `int_size` as well, just to be safe.
