Won't add

• Append - D already lets you append arrays using ~=
• AsEnumerable - This project only uses arrays
• ElementAt - [n] gets the element at n-th position
• Empty - [ ] creates an empty array
• Reverse - array already has a property with the same name that does the same thing
• SelectMany - Just run Select multiple times
• SequenceEqual - [] == [] does the same thing
• Single - What's the point? Just check the length and use first
• ThenBy - D doesn't have deferred execution
• ThenByDescending - same as ThenBy
• ToArray - Same as AsEnumerable
• ToHashSet - Same as AsEnumerable
• ToList - Same as AsEnumerable
• ToLookup - Same as AsEnumerable
