Some improvements
Added Append and Prepend extension methods to IEnumerable<T>  for any T. Facilities are provided by the Utilities assembly.
Added an overload of With(...) for pattern matching which allows for a value of TResult, rather than a function returning a value TResult to be supplied for a type case.
