For example I'd be happy if I could generate structs dynamically, based on string input.

This would mean that we could automatically create true struct-based components with channel fields from the shell like syntax used in the examples in the README (like "echo > {o:foo}" to write to an out-port named "foo"), so that connecting an out-port to an in-port would go like:

Process2.InFoo = Process1.OutFoo

This is not possible with Go's reflection though, so right now, based on these shell like patterns, we can only populate maps (InPorts and OutPorts) of the process, such that the above code example becomes:

Process2.InPorts["foo"] = Process1.OutPorts["foo"]
