Composite Data Types as Algebra, Logic Recursive Types Algebraic Data Types Christine Rizkallah CSE, UNSW Term 3 2020 1 Composite Data Types as Algebra, Logic Recursive Types Composite Data Types Most of the types we have seen so far are basic types, in the sense that they represent built-in machine data representations. Real programming languages
COMP3161/COMP9164 Supplementary Lecture Notes Abstract Machines Gabriele Keller, Liam O’Connor October 20, 2019 1 Abstract Machines Abstract machines are a theoretical model of a calculator, typically consisting of a set of states, including initial and final states, and a set of machine operations, which manipulate the state of the machine. They are an important concept

COMP3161/COMP9164 Supplementary Lecture Notes 1 Subtyping Subtyping Gabriele Keller, Liam O’Connor November 11, 2019 With type classes, the programmer can use the same overloaded function symbol both for addition of floating point values and integer values, and the compiler will figure out which to use. However, the following expression would still be rejected by the
COMP3161/COMP9164 Supplementary Lecture Notes Type Safety and Exceptions Liam O’Connor November 1, 2019 When we define a static semantics for a language, we wish that static semantics to imply some properties about the dynamic semantics. In this notes, we will discuss what properties are, how we can classify them, and the kinds of properties we

Implicitly Typed MinHS Inference Algorithm Unification Damas-Milner Type Inference Christine Rizkallah CSE, UNSW Term 3 2020 1 Implicitly Typed MinHS Inference Algorithm Unification Implicitly Typed MinHS Explicitly typed languages are awkward to use1. Ideally, we’d like the compiler to determine the types for us. Example What is the type of this function? recfunf x=fstx+1 We
