All of the built-in sequence types (list, set, frozenset, tuple) inherit
from one of the ABC's in collections, collections.Sequence is probably
the right one. Would using isinstance(arg, collections.Sequence) work?
This just feels... abusive, definitely not idiomatic.

What is values? I assume in this else block it's a string? If it is a
string then just setting retval = values should be sufficient.
