| Jarsolav, is this something that should be added to Octave?

You need to write

  v = cell (expected_nargout, 1);

  [v{:}] = func (...);

Does

  v = cell (expected_nargout, 1);
  v{:} = func (...);

work in Matlab?  If so, I think that's a relatively new addition and
in my opinion doesn't really fit with the rest of the language.
