message send while debugging.  (In a slightly different way.)  Showing
these intermediate/returned values is a great idea.

as + and *.  I'm not sure if this was intentional, but I don't think you'd
want to leave these out.

(Also, the thin border just above the "returned" pane makes it difficult
to resize the source code pane to be larger, but I admit that's getting
