Lecture 6: Introduction to Static Analysis
In this lecture we discuss the need for type checking, or more broadly, static analysis, i.e. the application of analyses to the static representation (text, AST) of a program.
- Type checking
- Schema checking
- Defining type checkers
- Name binding
- Name resolution
- Scope graphs

This paper develops a constraint language for description of type system using scope graph constraints for the definition of name binding. These constraints are the basis for the NaBL2 language.
