Nice! As soon as the Pharo11 dev cycle starts, I want to use it and look into the state of serialising clean blocks.

(Clean blocks are not enabled by default in Pharo10, but I want to push for finishing that soon in Pharo11).

Another change I am looking into is to allow Slots on all classes… we can not not have indexed instance variables
in some classes, but with Slots we can define non-indexed “instance variables” that store somewhere else.

E.g. we could implement a subclass of Slot that would realise a Variable “source” on CompiledMethod that would
abstract away source code storage mess (just as an example what this can do, not to say that we should do exactly that).

Or have a Slot that stores into a property API as we have it on all the Structural entities (from classes down to compiledMethod).

Fuel for now just ignores the whole “First class Variable” concept and serialises the “raw” view of indexed instance
variables… (which is the right thing to do now), but that would not work here anymore.
