Alternatively, array_combine() could be made variadic, adding your proposed
behavior (which is more in line with the current behavior of
array_combine() than array_map()).

Speaking of,

Just to be clear, do you mean the result would be:
    array($keys[0] => array($vals0[0], $vals1[0], ...),
          $keys[1] => array($vals0[1], $vals1[1], ...),
          ...)

so the i-th item in the result would be an array with the i-th items of
each value array, and the i-th item of the key array as the key?
