Re: [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?

I just replied to that in the ticket :-) HTH. Regards, -- Joel de Guzman http://www.boost-consulting.com http://spirit.sf.net
