// @hammett: "Linq doesn't have a Partition operation that returns two sets? (filtered/complement).. sad!"

// GroupBy can be seen as a partition. We specialize it to have exactly two groups:

public static class PartitionExtension
{
    public static Tuple<IEnumerable<T>, IEnumerable<T>> Partition<T>(this IEnumerable<T> enumeration, Func<T, bool> criteria)
    {
        var whole = enumeration.GroupBy(criteria);

Three anti-hero technologies (Microsoft's new Windows 8 Metro tablets, the Command-Query Responsibility Separation architectural pattern, and the opensource functional programming language Erlang) snap together to form a delightful, maintainable and scalable system. It's not a mainstream or obvious choice, but I'll show you in an opensource end-to-end application how they fit. This will be my technology stack of choice for years to come, and I look forward to showing you why.
