So Erlang's ioslist are cool, because you can write code [like this.](https://junglecoder.com/linx/selif/ymc1vqa1.png "Fairly nice code")
And it can generate ugly nested balls of lists and binaries [like this.](https://junglecoder.com/linx/selif/40p9f81o.png "An ugly ball of nests lists and binaires")
Which then can turn around and generate the HTML page you're looking at, with a lot of speed.
