[boost] [fusion] value_at of transform_view

Hi,

I'm trying to fix ticket #1396: http://svn.boost.org/trac/boost/ticket/1396
The problem is that `result_of<identity(int)>::type` is triggered,
where `int` is the result of `value_at` invocation into `vector<int, int>`.

Now, I don't know what value_at of transform_view should return.
In fact, I don't know even what value_at means.
value_at semantics says "Returns the actual type at a given index from the Sequence."
What is "the acutal type" of transform_view?
(BTW, STL iterators don't have something like value_at.)
Any hint?

Regards,
