 value could be integer values, boolean values, bytes (for memcpy), function ID
 (full name + concrete type)
 
 ## Current Plan
 
-1. Write out the syntax-directed type checking/inferencing rules. Fix the rule
-   for type variable instantiation.
-2. Update the library dependencies and rewrite some of the type checking code.
-3. Design the symbol resolver API.
-4. Move tests from code to external files to cleanup the code.
+Type checking:

+- [x] Basic interface for symbol resolver.
+- [x] Track location information in context object (for diagnostics).
+- [ ] Refactor old expression and statement type inference code. (anto)
+- [ ] Error diagnostics utilities. (pca)
+- [ ] Move tests to external files, write scripts for testing. (pca)
+- [ ] Implement function type checking (instantiate bounded type parameters),
+    loop unrolling, type inference for lists with virtual objects. (pca)
