{{alias}}( [options] )
    Returns an iterator which generates a Lucas sequence.

    The returned iterator can only generate the first 77 Lucas numbers, as
    larger Lucas numbers cannot be safely represented in double-precision
    floating-point format.

    If an environment supports Symbol.iterator, the returned iterator is
    iterable.

    Parameters
    ----------
    options: Object (optional)
        Function options.

    options.iter: integer (optional)
        Number of iterations. Default: 77.

    Returns
    -------
    iterator: Object
        Iterator.

    iterator.next(): Function
        Returns an iterator protocol-compliant object containing the next
        iterated value (if one exists) and a boolean flag indicating whether the
        iterator is finished.

    iterator.return( [value] ): Function
        Finishes an iterator and returns a provided value.

    Examples
    --------
    > var it = {{alias}}();
    > var v = it.next().value
    2
    > v = it.next().value
    1
