Comparing With C#

The goal of this project is not to claim that Haskell is simply "C# but more functional."

Instead, it helps answer a narrower question:

If the C# repo is teaching a concept with plain C# and LanguageExt, what does that same concept look like in a language where those abstractions are native?

Useful Translation Heuristics

Option / Maybe

  • C# null checks and Option<T> examples usually map to Maybe

Either / Validation

  • fail-fast error channels map naturally to Either
  • accumulated validation often becomes Either [String] a or a dedicated validation type

Reader

  • composition-root or dependency-threading discussions often map to explicit environment passing or Reader

State

  • explicit immutable state threading in C# maps naturally to pure state transitions in Haskell
  • once the workflow grows, State can express the same idea more compactly

IO boundaries

  • what the C# repo frames as "push effects to the edge" is still the right idea here
  • the difference is that Haskell has a language-level effect boundary in IO
