First : discuss term project assignment.

Second : discuss the current state of the dickinson language class project :

• move to github/BenningtonComputing - team SICP2019 , repo dickinson-language ... for those interested in the group
• examples ... both simple code snippets & corresponding scheme
  • will become test cases
• grammar

How should scope of variables within functions work? And how does that connect to scheme? Discuss "syntax" vs "semantics" ...

Third : best use of class time in the next few classes?

• Work on dickinson language?
• Look at SICP chapter 4 "Metalinguistic Abstraction"?]
• Look at our term topics (data structures, scope, syntax, recursion, ...) in some other languages?
  • Janet (lispy in many ways, but arrays not cons + hash tables + PEG (grammars))
  • Clojure ... lispy built on JVM ; mostly immutable + messages
  • Haskell ... purely functional

aside

• advent of code ... midnight Dec 1 !
