-/* Implementation helper: a struct that looks like a tuple.
-   See timemodule and posixmodule for example uses.
-
-   The structseq helper is considered an internal CPython implementation
-   detail.  Docs for modules using structseqs should call them
-   "named tuples" (be sure to include a space between the two
-   words and add a link back to the term in Docs/glossary.rst).
