Toot

Written by Anthony Cowley on 2024-10-14 at 13:42

A reaction I have when reading a new-to-me #haskell library that I don't like is that my interest tends to shut down when I see template haskell. One reason for this is that generally you can be navigating a library, following the types to understand what's happening, and then you hit something whose type is Name -> Q [Dec] and you don't know what you're getting. If the TH is going to break with the next GHC, you don't know what fixing it yourself will involve.
