  • Stack-safety for free?

    That's an awesome tagline! I have a Haskell background and was alluding to "Monads for free" from the free package when picking the title "Stack-safety for free?" Alluding to Rust's "fearless concurrency" seems so much more appropriate though.

    https://hackage.haskell.org/package/trust-chain is a little more out there, but the most interesting to me personally. There are two ways to think about it, each useful to different audiences. On one hand, it can be seen as a tree where the node structure and leaf type are type level parameters, and every internal node is signed by the private key corresponding to the public key at that node. In Haskell, it can be seen as a free monad where every layer is signed in that same way.
