##### push_front

###### Description

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

###### Synopsis

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

Table 1.72. Parameters

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

###### 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 beginning. The elements are in the same order as they were in `seq`.

###### Complexity

Constant. Returns a view which is lazily evaluated.
