Intro is a modern Prelude which provides safe alternatives for most of the partial functions and follows other best practices, e.g., Text is preferred over String. For String overloading the extension OverloadedStrings should be used. Container types and Monad transformers are provided. Most important - this Prelude tries to keep things simple. This means it just reexports from base and commonly used libraries and adds only very few additional functions. Everything is exported explicitly to provide a stable interface and to improve the quality of the documentation.
