    Nice! Thanks for including a comparison with my package typelevel-rewrite-rules. Since my package indeed struggles with infinite loops introduced by self-triggering rewrite rules, I would like to better understand why your package doesn't suffer from that same problem.

    When writing a typechecker plugin, you can eliminate constraints from the user's program by providing an implementation of the corresponding dictionary. The way you provide that dictionary to ghc is by providing a core expression; for example, this evCast futureDict co expression has type EvTerm, whose first constructor takes an EvExpr, which is a synonym for CoreExpr.

    Until then, I guess we can simply poll. Here's a GitHub Action I wrote today which checks if the latest report for a given package includes a failure: https://github.com/gelisam/typelevel-rewrite-rules/blob/main/.github/workflows/check-hackage-matrix.yml
