I tried it and Peter seems to be correct. IDL pass by reference seems
to work the way it should and not the way it is documented.

While we are on the subject of documentation, my personal favorite is
the way in which the /NO_COPY keyword is documented for the WIDGET_*
routines. The paragraph given leaves much to the imagination. On the
other hand, the documentation for the HANDLE_* routines makes the
operation of this keyword very clear.

IMHO, the documentation is much better than it used to be, but there
is room for improvement.
