Yea, it's a game i often play. "Boy it would be nice if i could do X" where X is something like `and_then`, and then i go look it up in the stdlib and.. it's there.

Generally speaking these methods are super helpful and someone else already thought of it. From my experience at least. .. also this article was infuriating hah.
