Parametricity guide

Open hdgarrood opened this issue 8 years ago • 0 comments

This would cover questions such as

  • Why is there only one possible Functor Tuple instance
  • How can we make an educated guess at what foldJson from argonaut does just by looking at the type signature

If anyone has any other suggestions for things which would be useful to cover, please comment and let me know.
