The automatic diagrams are great. Almost worth using a library like this just for that, since then you know the diagram actually reflects the implementation.

Yes, all my examples have state diagrams, they are automatically generated and are an effective way for me to understand the structure of the program.

shouldn't the check pin example end with 'exit' rather than 'ready'?

    .{ Atm.checkPin, Atm.session, Atm.ready } } }),
It was the diagram that made me think this.

Haha, this is just a demo, written casually, you can change this to exit, and then as you expected, the program will exit directly.

Try modifying it yourself, you will fall in love with this way of programming.
