[Pharo-project] Next step in cleaning DataStream

So, so far we have removed SmartRefStream, deprecated ReferenceStream and integrated Fuel. The ONLY remaining user for DataStream is Monticello. We do not want to replace that yet because Fuel may still change the format and we do not want to break monticello versions. But, my question is now...should we clean DataStream and assume its only usage will be the definitions of Monticello? becuase I true, I think we may be able to remove DiskProxy and all its users, togethet with lots of methods like #objectForDataStream: what do you think? -- Mariano http://marianopeck.wordpress.com
