Part 2/3/4 should be way more broadly useful to haskellers, because I want to cover things like how I build components and how I use `mtl` style and the `ReaderT` pattern to make writing `servant` handlers easy and type-enhanced. If that stuff is more interesting to you I'd recommend these two talks: - Ben Kolera - Monad Transformers - Next Level MTL Thanks for reading!

Hey sounds like you're going to be bored with part 3! I basically do that, but only use typeclasses on monads, without `lens`. I haven't actually fully grokked lenses/prisms/generic-lens yet (which is why I'm avoiding them), but George Wilson's talk on Classy Optics was huge to me (there's also one more talk by Ben Kolera which is relevant as well) . At that point I'd already been doing something similar but without `lens` (just stringing together accessors) and didn't feel too ashamed. I'm not sure which part you meant about why my approach is needed, but it's definitely *not*! I can justify *why* I wrote the article like I did: - The basic `Task` to show how - The `Task f` to be abl…
