Why Dependent Types Matter

Companion code in Agda, Idris ans Haskell for "Why Dependent Types Matter" paper by Thorsten Altenkirch, Conor McBride and James McKinna. Original code in the paper uses Epigram language, which is no longer maintained or even available. Thus I made a rewrite to modern functional languages. For more information see blog posts about Agda code, Idris code and Haskell code.
