Examples: Functions as Values

	..	Index to Examples.
	8/01	Compile global first-order functions into stack machine code. Function as parameter and result value.
	8/02	Euclid's algorithm, function as a variable value.
	8/03	Mutually recursive functions, function as a variable value.
	8/04	Block scopes, now declare before use required.
	8/05	Shadowing, now declare before use required.
	8/06	Semantic errors in functions.
	8/07	(Flawed) function composition.
	8/08	Compile nested first-order functions into stack machine code. Function value == address + display. As parameter only.
