- Statements vs. Expressions
- Removes bad "magic" from programming
-
(+ (- 5 1) (/ 6 2))
does not require special syntactic support, as opposed to(+ 4 3)
- Entry points (what order things are executed in)
- Sometimes the program is just executed in order, and sometimes the entry point is specially delineated
