My memory of Smalltalk 72 is pretty fuzzy. (I remember the character set
included eyeballs, that communication was stack based, a bit like Forth, and
therefore flexible but error prone, and not much else.) My guess is that
most people reading this know even less. Could you summarize what were the
important ideas in Smalltalk 72 that have been lost/ignored? Like its
inheritance scheme.

Best,
