Hi,

Already in Pharo3 all instance variables are described using meta-objects (so called slots).

To make it easier to access the slots, I added some simple methods to ClassDescription on 4.0 043,
Now we can do e.g.:

Context slots
Context allSlots

Point hasSlotNamed: #x
Point slotNamed: #x

As Camille noted, we need a different API on the Objects to read and write slots.

We came up with:

#readSlot:
#readSlotNamed:
#writeSlot:value:
#writeSlotNamed:value:
#writeToSlot:of: �� �� �� �� �� �� �� ��(this is what the compiler generates to reflectively write a slot)

e.g.

5@3 readSlot: (Point slotNamed: #x)

5@3��writeSlotNamed: #x value: 7

This is in the issue tracker:��https://pharo.fogbugz.com/f/cases/13418/reflective-API-for-Slots-on-Object
