{{alias}}( alternative )
    Returns the enumeration constant associated with a Z-test alternative
    hypothesis string.

    Downstream consumers of this function should *not* rely on specific integer
    values (e.g., `TWO_SIDED == 0`). Instead, the function should be used in an
    opaque manner.

    Parameters
    ----------
    alternative: string
        Alternative hypothesis.

    Returns
    -------
    out: integer|null
        Enumeration constant.

    Examples
    --------
    > var out = {{alias}}( 'greater' )
    <number>
