Charleston Lean Proof Assistant Meetup

Lean is a functional programming language with a highly expressive type system. It can be used to produce performant programs that are guaranteed to meet their specifications, which proves that a large class of bugs cannot exist in your program. It can also be used to interactively prove theorems in mathematics. This meetup is for enthusiasts to join together to learn, code, and share their experiences with Lean.

For our January meeting we will cover a major topic in functional programming, namely monads. We will give background and definitions for this abstraction, many examples, and will also show where Lean can shine by proving some of the monad laws in some of the examples.
