Notes and Exercises from Chapter 5 of Haskell Book

Benefits of a type system:

• Many errors caught before program execution, at compile time
• Compiler optimizations
• Documentation of programs
• Less code to write because you don't have to validate data at every step

Many, perhaps most, programming languages have type systems that feel like haggling with a petty merchant. Haskell provides a type system that more closely resembles a quiet, pleasant conversation with a colleague than an argument in the bazaar.
