Take a look at https://docs.python.org/3/faq/programming.html#why-am-i-getting-an-unboundlocalerror-when-the-variable-has-a-value

What's happening is that because `a |= x` is treated as an assignment, i.e `a = a | x`. The compiler treats it as a local variable, but since it hasn't been initialized in inner() before it reaches `a |= set(["A"])` it fails with UnboundLocalError.
