    Discussing “Computational Types from a Logical Perspective”

    This is a sequel to a paper by Moggi that I discussed some time ago. That paper discussed side effects, which are, roughly speaking, anything interesting that a program does other than map inputs deterministically to outputs, such as failure to terminate with a value, taking in user input, or producing output before the computation…

    Discussing “Isabelle/HOL: A Proof Assistant for Higher-Order Logic”

    In the world of interactive theorem provers two systems stand out for their maturity and wide adoption. One is Rocq, until recently known as Coq, about which I have written previously; Isabelle/HOL, the topic of this week’s reading, is the other. Rocq is one of a number of systems (for example, Lean) based on Martin-Löf’s…
