COMP3161/COMP9164 Syntax Exercises Liam O’Connor September 26, 2019 1. (a) [⋆] Consider the following expressions in Higher Order abstract syntax. Convert them to concrete syntax. i. (Let (Num 3) (x. (Let (Plus x (Num 1)) (x. (Plus x x))))) ii. (Plus (Let (Num 3) (x. (Plus x x))) (Let (Num 2) (y. (Plus y (Num […]

λ-Calculus Church Encodings λ-Calculus Dr. Liam O’Connor University of Edinburgh LFCS UNSW, Term 3 2020 1 λ-Calculus Church Encodings λ-Calculus The term language we defined for Higher Order Abstract Syntax is almost a full featured programming language. Just enrich the syntax slightly: t ::= Symbol | x | t1 t2 | λx. t (variables) (application)

COMP3161/COMP9164 Supplementary Lecture Notes Syntax Gabriele Keller September 26, 2019 1 Concrete Syntax versus Abstract Syntax The concrete syntax of a programming language is designed with the user/programmer in mind: it should be well structured and easy to read. The parser checks if a given program adheres to the concrete syntax and translates it into

COMP3161/9164 20T3 Assignment 1 MinHs Version 2.6 Marks : 17.5% of the mark for the course. Due date: Friday, 30th of October 2020, 12 noon Sydney time Overview In this assignment you will implement an interpreter for MinHs, a small functional language similar to ML and Haskell. It is fully typed, with types specified by
Overloading Subtyping 1 Overloading and Subtyping Christine Rizkallah CSE, UNSW Term 3 2020 Overloading Subtyping 2 Motivation Suppose we added Float to MinHS. Ideally, the same functions should be able to work on both Int and Float. 4+6 :: Int 4.3 + 5.1 :: Float Similarly, a numeric literal should take on whatever type is
