Using PLAI-Typed

• Talk about testing in the first Dailies
• Double check if there's value in Dyvig section 2.4, 2.5, 2.8, 2.9 and explain lambda
• Add questions to Dailies on tables and quasiquote (or prelude in later assignment)

• Add to Datatypes notes: binary tree!
• New testing concepts (see PLAI docs)

Syntactic Sugar Examples:

• in C, a[i] is syntactic sugar for *(a + i)
• in Python, x + y is syntactic sugar for x.add(y)
• in Haskell, [f x | x ← lst] desugars to map f lst

Evolution of Language <grin>

• Update AE with breakdown:

  concrete {...} -> reads ('+ 3 6) which is s-expreesion 
                 -> parses to (add [num 3] [num 6]) which is abstract syntax
                 -> interprets to 8 which is the result!

Idea: have them build the continuation-based web server (uses delimited continuations) as an assigment
