    Defining data structures in data-flow diagrams

We have seen, how we can define functions in data flow diagrams, but can we go further and define complex data structures using only the essential language elements of data-flow diagrams. Well as it turns out: yes, you can define algebraic data types in a day to day data-flow diagram and I want to show you how it is done.
But first a note on algebraic data types (ADT). If you don't know what those are, don't feel bad, they are rather simple. I will first show you how we define ADTs and what their benefits are, before I will introduce them into data-flow diagrams. If this seems rather odd, why would anybody want to do this, I can tell you, that it taught me a lot about the structure of data and how they work hand in hand with functions. I hope to also discuss how to create a powerful meta-language and the requirements to create those are so fundamental, that they apply to every language even our data-flow language.
So let's start with a simple definition of

    Functions are data-flow time machines

Today data-flow diagrams are something every CS student and programmer has seen. It is a nice way of visualizing the general flow of data through an application. But it is rarely more than that. A few reasons for this might be an inconvenience in displaying details. They tend to get big!
Another problem is the rather limited language which is incapable of describing some fundamental ideas of CS like lambda functions. Would you know how to draw a lambda function in a data-flow diagram? If you ever heard of string diagrams, you might be able to do so, but most programmers wouldn't recognize them.
I myself adore data-flow diagrams and I'm fascinated by what you can do with them even in an functional setting. That's why I want to show you, how you can build lambda functions in a data-flow diagram in a functional way and what this has to do with time machines. But first lets start with some simple examples to get used to functional data-flow diagrams. Here we have a rat
