###### Description

Returns a new sequence with another sequence inserted at a specified iterator.

###### Synposis

    template<
        typename Sequence,
        typename Pos,
        typename Range
        >
    typename result_of::insert_range<Sequence const, Pos, Range>::type insert_range(
        Sequence const& seq, Pos const& pos, Range const& range);

Table 1.66. Parameters

Parameter | Requirement | Description
--- | --- | ---
`seq` | A model of Forward Sequence | Operation's argument
`pos` | A model of Forward Iterator | The position to insert at
`range` | A model of Forward Sequence | Range to insert

###### Expression Semantics

    insert(seq, pos, range);

Return type: A model of Forward Sequence.

Semantics: Returns a new sequence, containing all the elements of `seq`, and the elements of `range` inserted at iterator `pos`. All elements retaining their ordering from the orignal sequences.

###### Complexity

Constant. Returns a view which is lazily evaluated.

###### Header

    #include <boost/fusion/algorithm/transformation/insert_range.hpp>
    #include <boost/fusion/include/insert_range.hpp>

###### Example

    const vector<int,int> vec(1,2);
    assert(insert_range(vec, next(begin(vec)), make_vector(3,4)) == make_vector(1,3,4,2));
