    In webapp2 they use webob.multidict.GetDict, which operates almost identically
    to werkzeug.datastructures.ImmutableMultiDict.

    The only difference is that in GetDict.items() by default it returns duplicate values,
    whereas in ImmutableMultiDict.items() by default it doesn't

    e.g. for GET /?foo=bar&foo=baz
        webob.multidict.GetDict.items() returns [("foo", "bar"), ("foo", "baz")]
        werkzeug.datastructures.ImmutableMultiDict.items() returns [("foo", "bar")]
