def iall(arrays, axis = -1):
    """ 
    Test whether all array elements along a given axis evaluate to True 

    Parameters
    ----------
    arrays : iterable
        Arrays to be reduced.
    axis : int or None, optional
        Axis along which a logical AND reduction is performed. The default
        is to perform a logical AND along the 'stream axis', as if all arrays in ``array``
        were stacked along a new dimension. If ``axis = None``, arrays in ``arrays`` are flattened
        before reduction.

    Yields
    ------
    all : ndarray, dtype bool
