Monkeying in the Meta

August 28, 2011 20:51:27.525

Michael van der Gulik has some interesting notes on playing around at the meta levels of Smalltalk:

I want to add more instance variables to Class. How difficult is this? Pretty. I suspect that for vanilla Squeak or Pharo, you'd need to carefully remake every single Metaclass instance and Class instance. For me, my Packages architecture means I only need to recompile my own private Metaclasses and all its instances which can be done safely.

Read the whole thing; Michael is working where angels fear to tread :)
