In emulation mode, given the following definition:
...
template <typename Container>
struct some_metafunction
{
    typedef BOOST_TYPEOF_TPL(
        Container().insert(
            typename Container::iterator()
          , typename Container::value_type()
        )
    ) type;
};
Which of the following types need to be registered?
1. The argument passed as `Container`
2. The result of `typename Container::iterator`
3. The result of `typename Container::value_type`
Almost forgot:
4. The result type of the expression passed into `BOOST_TYPEOF_TPL`.
(4) only.  BOOST_TYPEOF doesn't inspect
the contents of the expression.  Only
its result.
