Defining Keras models reminds me of the ugly ASP code I'd sometimes write
to create HTML in an object-oriented fashion. Writing plain HTML was
usually more pleasant and readable.

I suggested XML with that memory in mind. It's cumbersome for many tasks,
but Keras models in particular might be a good fit. Or YAML.
