title: F# open source projects
body: <p>I'm looking for some open source F# projects to learn from. 
  Something not snippets but full projects that are good representatives of F# features (i.e. pattern matching, discriminated unions, etc).</p>
  
  <p>My objective are mainly to see how all the features fit together, how the project is organized and how the problems are tackled from a functional perspective.</p>
