Ok well that at least has examples of the syntax. But not a single example of actually using the language to do anything. That is, no examples of actual code.

Ok well that at least has examples of the syntax. But not a single example of actually using the language to do anything. That is, no examples of actual code. It took a while to click through a link to an actual implementation on github, which had some test examples. None of which were documented. So idk? I'm not going to buy the ebook for $41 to find out. So to answer your original question: Liskell, despite being 13 years old and unmaintained, does actually have an accessible document that _explains what it is_.
