"defer { … }" implementation for Objective-C and C when __has_extension(blocks)

This all started because I was complaining about some uninitialized pointer value causing me grief[^mmap] and someone (explicitly trolling) said they always check pointers using:

int fds[2] = { -1, -1}; 
pipe(fds);
if (write(fds[0], pointer_to_check, sizeof(intptr_t)) == -1) {
    close(fds[0]);
    close(fds[1]);
    return not_valid;
} else {
