> inspectable and programmable from the ground up - that's worth preserving. This is what made me curious about the Smalltalk-based Squeak VM http://squeak.org/ http://squeak.org/. Its entire interface and stack was inspectable and manipulatable in real time. In practice it seemed a little buggy, though. If you installed Squeak programs too willy-nilly, pretty soon you'd get errors due to incompatibilities.
