Monads are fairly simple as well if you use C#'s brilliantly chosen names SELECT and SELECTMANY for the two relevant maps.

That's exactly it, SelectMany is what in .NET corresponds to flatMap in e.g. Java. (And, unlike the parent, I don't like the narrow scope of .NET naming very much, focusing on just the list monad (a.k.a. IEnumerable).)
