 DRAGON Semantic Checklist
 =========================
 
-[ ] 1. Semantic rules for Scoping
-[ ]    1.1. Local objects cannot be declared more than once
-[ ]    1.2. Local objects hide non-local objects with the same name
-[ ]    1.3. Non-local objects should be visible from inner scopes (unless a local object of the same name exists)
-[ ]    1.4. Function and procedure names exist in the scope they are defined (and not in their own scopes)
-[ ]    1.5. Local objects cease to exist once their scopes cease to exist

-[ ] 2. Semantic rules for Expressions
-[ ]    2.1. Expressions return typed-values
-[ ]    2.2. Objects must be declared before they used in expressions
-[ ]    2.3. Objects of different types cannot appear in the same expression (no type promotions)

 [ ] 3. Semantic rules for Statements
 [ ]    3.1. Statements do not return values
-[ ]    3.2. The test expression for IF-THEN, IF-THEN-ELSE, WHILE-DO must be Boolean-valued;
-[ ]         note that the Boolean type must be implicitly defined
-[ ]    3.3. The ELSE clause always binds to the closest IF (resolution of the dangling ELSE problem)

 [ ]    3.4. The variable type in FOR-DO must match the types of lower bound and upper bound expressions
 
 [ ] 4. Semantic rules for Arrays
-[ ]    4.1. Non-integer valued expressions cannot be used for indexing arrays
+[X]    4.1. Non-integer valued expressions cannot be used for indexing arrays

-[ ]    5.1. Function calls return values of type Integer or Real
+[X]    5.1. Function calls return values of type Integer or Real
 [ ]    5.2. Function must contain a "return" statement within its own body;

+            this is of the form: <function_name> := <expression>

 [X]    5.4. Functions are not allowed to update the value of nonlocal objects (via assignment statements)
 
 [ ] 6. Semantic rules for Procedures
 [ ]    6.1. Procedure calls do not return values
 [ ]    6.2. Procedures must accept exactly the same number of arguments as is
