Alan Kay wrote to the Squeak mailing list on 15 Jan. 2000:

You will be interested to learn that the very first version of Smalltalk (Smalltalk-72) had a completely extensible syntax (in fact the writing of a class also automatically supplied the grammar). This worked very well, except ... that too much freedom here leads to a Tower of Babel as far as other users are concerned. This has also been the experience with the few other really good extensible languages (like Ned Iron's IMP).

Extreme extensibility was removed in the next major design of Smalltalk (Smalltalk-76) in favor of a syntax that could read by anyone, regardless of how many classes had been defined ... i.e., getting stronger meanings turned out to be more important in the end than making language structures fit the task.

That being said, I think this process went too far with Smalltalk-80, and needs more experimentation for the next generation, most of whom will be "occasional scriptors", and who need more readable (especially "gistable") code.

Squeak Class Size History contains an interesting overview of the new additions and the number of classes in each version of Squeak.
