###### Description

Returns a new sequence with an element added at the end.

###### Synopsis

    template<
        typename Sequence,
        typename T
        >
    typename result_of::push_back<Sequence, T>::type push_back(
        Sequence const& seq, T const& t);

Table 1.81. Parameters

Parameter | Requirement | Description
--- | --- | ---
`seq` | A model of Forward Sequence | Operation's argument
`t` | Any type | The value to add to the end

###### Expression Semantics

    push_back(seq, t);

Return type:

- A model of Forward Sequence.

Semantics: Returns a new sequence, containing all the elements of `seq`, and new element `t` appended to the end. The elements are in the same order as they were in `seq`.

###### Complexity

Constant. Returns a view which is lazily evaluated.
