Lecture 8: Constraint Semantics & Resolution
In this lecture we study constraint-based static semantic analysis using the scope graph framework for name resolution.

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.
