 .. note::
    ``raw`` specifier is restricted for usages that the axes to be reduced are put at the head of the shape.
-   It means, if you want to use ``raw`` specifier for at least one argument, the ``axis`` argument must be ``0`` or a contiguous increasing sequence of integers starting from ``0``, like ``(0, 1)``, ``(0, 1, 2)``, etc.
