PS2: Another really annoying problem is the following: he saved all his (really important) scripts using Script Manager as a FUEL. Moving between 4.0 and 5.0 FUEL stops working (version incompatibility) - this is really not cool, why would a newer FUEL not be able to read older FUEL. He ended up copying string data by opening the binary FUEL file in a text editor. it is like that from the beginning. I guess there was the fear keeping everything compatible would be a huge amount of work. But it is indeed an annoying thing. The usual way to deal with it is open pharo4 and materialize the fuel file then upgrade fuel to the version pharo5 uses and save again.
Norbert Yeah, but this is silly: it goes against the principle of a persistence format: to save data for future use. [ I knew this already, I never agreed with this principle ]. Me too - believe but my scenario was not really heard. I think that it would be good to have some strategies to represent different objects representation but fuel will be slower. Mariano was fighting against speed and speed and speed. and he did it well. Like I described in the email, after upgrading, we were unable to run the old image - catch 22.
