Another thing that we might want to fix in the new release is the
ability to do

  return (foo, bar)

instead of

  values[0] = foo
  values[1] = bar

in the Expression class in Python.

Johan hinted that it would be possible to implement this.

On the other hand, one can argue that the simplified Expression
interface (using C++ string expressions) is already simple enough for
simple cases and that one should need to assign to values when
subclassing Expression to make it consistent with the C++ interface.

Opinions?
