[Pharo-dev] [Pharo4][Slots] Migration of instances now Slot-aware

[Marcus Denker]

Hi,

Thanks to Max, the instance migration when changing a class with existing 
instances is now
aware of slots.

e.g., you can 

Object subclass: #A
        slots: { #iv => TestSlot }
        classVariables: {  }
        category: ‘Playground'

do A new, change iv, then change the definition to a normal instance var:

Object subclass: #A
        slots: { #iv  }
        classVariables: {  }
        category: ‘Playground'


==> instance is migrated while keeping the value.

TODO (to have a first complete version)
        -> hidden slots (slice needs another pass)
        -> build hook
        -> call #initialize: on all Slots after #new when requested.
