Hello !So my colleagues and I have some linear logical language engineering in various states of immaturity at github.com/hopper-lang
Last fall Jeff polakow presented a paper at Haskell symposium or Icfp (forget which) for embedding linear types in Haskell , might be worth googling around for a copy of that paper (Google scholar might get you a non paywalled pdf)
There's some cool stuff related to this I hope to share with the community in the near future, but that's all I can offer off the cuff
