{{alias}}( x, mask, values, mode )
    Replaces elements of an array with provided values according to a provided
    mask array.

    In broadcasting modes, the function supports broadcasting a values array
    containing a single element against the number of truthy values in the mask
    array.

    In repeat mode, the function supports recycling elements in a values array
    to satisfy the number of truthy values in the mask array.

    The function mutates the input array.

    Parameters
    ----------
    x: ArrayLikeObject
        Input array.

    mask: ArrayLikeObject
        Mask array. If a mask array element is truthy, the corresponding element
        in `x` is *replaced*; otherwise, the corresponding element in `x` is
        "masked" and thus left unchanged.

    values: ArrayLikeObject
        Values to set.

    mode: string
        String specifying behavior when the number of values to set does not
        equal the number of truthy mask values. The function supports the
        following modes:

        - 'strict': specifies that the function must raise an exception when the
        number of values does not *exactly* equal the number of truthy mask
        values.
        - 'non_strict': specifies that the function must raise an exception when
        the function is provided insufficient values to satisfy the mask array.
        - 'strict_broadcast': specifies that the function must broadcast a
        single-element values array and otherwise raise an exception when the
        number of values does not **exactly** equal the number of truthy mask
        values.
        - 'broadcast': specifies that the function must broadcast a single-
        element values array and otherwise raise an exception when the function
        is provided insufficient values to satisfy the mask array.
        - 'repeat': specifies that the function must reuse provided values when
        replacing elements in `x` in order to satisfy the mask array.

    Returns
    -------
    out: ArrayLikeObject
        Input array.

    Examples
    --------
    > var x = [ 1, 2, 3, 4 ];
    > var out = {{alias}}( x, [ 0, 1, 0, 1 ], [ 20, 40 ], 'strict' )
    [ 1, 20, 3, 40 ]
    > var bool = ( out === x )
    true
