Do you really want this? Do you really want the compiler crying every
time you write something like the following (just an example)

while ( get_data (...) && (p = malloc (...))) {
  ...
}

well, you could write something like

while (get_data (...)) {
  p = malloc (...);
  if (!p)
    break;
  ...
}

but the first one seems to be more clearly to me...
