Yeah, I was thinking about that when I wrote the comment. They were most useful for `Observable` objects for event handling in swing; you don't really need that with C# events.

There are still uses though. Lambdas are the future, but there are lots of OO-first libraries that are still quite popular. It'd be nice to create e.g. `new Newtonsoft.JsonConverter() { ReadJson() {...} WriteJson() {...}}` etc on the fly sometimes without needing separate classes.

It's possible in F# though, so nothing dotnet specific is preventing it.
