+Subject: [PATCH] Fixup for Python 3.10
+
+Closes issue #109.  Long story short: a few names from collection are
+now moved to collection.abc exclusively starting in Python 3.10. The
+only name this app uses from there that was moved is
+`collections.Iterable`.  Python versions starting from 3.3 support both
+`collections.Iterable` and `collections.abc.Iterable` as the way to refer to
+this class, which Python 3.10 being the first one to drop
+`collections.Iterable`.  So.. we just work around this API quirk
+and always refer ot it as `collections.abc.Iterable`.
