    //! This method is an alias to `length` provided for convenience and
    //! consistency with the standard library. As an alias, `size` is not
    //! tag-dispatched on its own and `length` should be customized instead.

    //! -------
    //! @include example/size.cpp
    BOOST_HANA_INLINE_VARIABLE constexpr auto size = hana::length;
