Dale,

I fully agree with all you said. There is something I would really like to
know and it's about the exact type of primitive objects that can
successfully be serialized from Pharo to GemStone (are these the tests of
STONWriterTests?) . That is... the tempvars 'x' and 'y' of your example. I
think I remember you saying there were some problems with certain type of
objects....
