• Kind equalities in GHC, based on the ICFP'13 paper
• Visible type application in GHC, based on the POPL'16 submission
• Glambda, a lambda-calculus interpreter built with GADTs, useful as a case study
• A new Coercible solver, already part of GHC
• The units package, a domain-specific type system for dimensional analysis
• Roles, as based on the ICFP'14 paper, already part of GHC
• Closed type families, implemented in two major commits, as based on the POPL'14 paper
• The singletons library, which allows for automatic derivation of declarations that support dependent types in released versions of GHC

• Eiger: Auditable, executable, flexible legal regulations. Alexander Bernauer and Richard A. Eisenberg. Posted on arXiv and presented at Haskell Symposium 2022.
• System FC, as implemented in GHC. This is a summary of the internal language in GHC, as implemented. (pdf)
