Presumably "sequence", which fits the other assumption that you noted:
that calling 'iter' on it will produce a non-destructive iterator.

I hope that code is never used on older Pythons that don't have
exception chaining, given that it has a bare except in it. Actually, I
hope that code is never used at all.
