There's nothing wrong with it.  A typedef declaration is allowed
wherever any other declaration is allowed, except in the condition of
a 'for', 'if', 'switch' or 'while' statement.

I don't see any requirement on the order of destruction of sequence
elements, so I think it can be either 3, 1, 2 or 3, 2, 1.
