Oh, that's very nice, and just the kind of functionality I've been wanting for some time.

That was something I was recalling from a very old project though. I'm not sure right now when that was exactly. Maybe it wasn't in the language yet at the time, or was a new feature still and I didn't find about it, or it wasn't in Mono yet.

I've not done C# in a long time, so no doubt I missed a lot of developments.
