------------------------------------------

	We've already seen several programs that are *syntax directed*
		 e.g., free-vars, bound-vars, lexical-address, 
                        strength-reduce

	Now we'll do the obvious other program: an interpreter

------------------------------------------
		WHY?

Use interpreters to:

	- explain semantics of features

	- play with behavior of features

	- play with changes to features


		HOW

Plan:
	- start with simple interpreter

	- add features
------------------------------------------

        applications of this idea:
                programming languages
                scripting languages for programs (e.g., for a spreadsheet,
                                                editor, games, etc.)
