I was sure something else saved the world ( :) ) too, but I couldn't remember. Of course Lisp and Smalltalk do it. It is a bit of a risk doing it in Forth because memory corruption is more likely, but I think it can work with careful, not-too-simple saving code -- checksums perhaps.

Squeak is another thing I "should have" properly tried. It was the basis for this 3D environment where, instead of sending all the data to all clients, code snippets were sent instead. The clients were synchronized so they all rendered the same. Moving around made me dizzy, though.
