Talking Points

Recent interactions between the hosts and their guests.

81: Torsten Grust
Q: What is the potential for compiling imperative languages into SQL, and what are the practical limits?
He explains that compilers can translate imperative styles into recursive CTEs or equivalent SQL representations, enabling near-native execution inside the database, though some higher-order patterns (like CPS-style code) need de-functionalization before targeting SQL.
81: Torsten Grust
Q: Are comprehensions expressive enough to replace SQL constructs, or is SQL still the practical backbone of querying?
He argues that monad comprehensions can express nearly all SQL constructs, and that comprehensions offer a uniform, executable framework that can transform and optimize queries, while acknowledging some SQL features like recursive queries require careful handling.
81: Torsten Grust
Q: So Torsten, how did you first get in touch with Haskell and when was that?
He describes early exposure in the 1990s, with Lisp and FP at Konstanz, then returning to Haskell in the late 1990s and later adopting GHC/GHCI as it became available, which deeply influenced his view of teaching and research.
80: POPL 2026 - Part 1
Q: What is choreographic programming and why is it interesting in the context of Popl?
Choreographic programming aims to present distributed systems programming in a way that resembles single-program development, allowing tooling to split the program into server and client components while maintaining a straightforward, sequential appearance.
79: Peter Thiemann
Q: Could you share a moment about Arrows and your experience with web programming in Haskell?
During a pizza lunch with John Hughes, he explained Arrows as a solution for web programming limitations in monads, which inspired me to explore monadic approaches and ultimately design a monad-based system to manage web interactions in a functional way.
