Hmmm, I guess the array updates of <https://www.open-std.org/jtc1/sc22/wg14/www/docs/n2906.pdf> and __lengthof__ supporting array parameters don't need to come with a change to sizeof. If one wants to learn the size of an array parameter, it's easy to define #define sizeof_array(a) (__lengthof__(a) * sizeof(*(a))) So, please ignore my proposal.
