Re: [boost] [typeof] registration question

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`. TIA! Cromwell D. Enage
