This document discusses how the Haskell programming language can help solve some of the hardest problems in modern software like reliability, modularity, performance, and concurrency. It notes that Haskell has been studied in academia for decades and is now being applied more in the real world through tools like the GHC compiler and over 750 open source packages. The document advocates that Haskell's philosophy and focus on functional programming allows developers to write code that is reliable, modular, and high performing.

4. Real World + Haskell
• Fast native-code compiler (GHC)
• Debugger, code coverage, profiling
• 750+ open source packages
• Mostly BSD-licensed, one-click install
• Friendly, active user community
• #haskell 12th biggest on freenode
