# Reading Group

In the weekly reading group session we discuss a paper from the literature. Currently reading group sessions are on Wednesdays at 11:00.

How the reading group works:

- all participants read the paper in advance
- at the start, the moderator makes a round collecting questions from the participants (without discussion)
- then we discuss those questions, typically in order of the section in the paper that they relate to

##### Staged Generic Programming

By Jeremy Yallop in ICFP'17

Moderator: Jeff Smits

Question: Can we apply this idea to generic traversals in Stratego?

## Past Sessions

##### A Path To DOT: Formalizing Fully-Path-Dependent Types

By Marianna Rapoport, Ondřej Lhoták in OOPSLA'19

Moderator: Paolo Giarrusso

We will focus not on the safety proofs, but on the language itself. In particular, I’d probably skip, at a first read, Sec. 2.3, 3.6, 5.1 and 5.2.

##### A Logic Programming Language with Finite Sets

By Agostino Dovier et al

Moderator: Arjen Rouvoet

Particularly interested in comparing sets with scopes in Statix

##### What are principal typings and what are they good for?

By Trevor Jim in POPL 1996

Moderator: Jeff Smits / Paolo Giarrusso

Of particular interest: Section 4 on separate compilation

##### A Foundation for Flow-Based Program Matching. Using Temporal Logic and Model Checking

By Julien Brunel, Damien Doligez, Rene Rydhof Hansen, Julia L. Lawall, Gilles Muller in POPL 2009

Moderator: Eelco Visser / Casper Bach Poulsen

##### Substructural Type Systems

By David Walker in Chapter 1 of Advanced Topics in Types and Programming Languages

Moderator: Eelco Visser (Andrew Tolmach)

Question: How are substructural type systems declaratively specified and how can we turn that into type checkers? How do these type systems fit in the scope graphs and Statix approach?

##### A Gentle Introduction to Multiparty Asynchronous Session Types

By Mario Coppo, Mariangiola Dezani-Ciancaglini, Luca Padovani, Nobuko Yoshida in International School on Formal Methods for the Design of Computer, Communication and Software Systems (SFM 2015) Formal Methods for Multicore Programming pp 146-178
