Markus, You illustrate why this is a bad design pattern to implement. It does not scale.

I attended a talk at PYCON UK that talked to the point of using object composition
rather then rich interfaces. I cannot recall the term that was used to cover this idea.

I also think that its a mistake to open a text file from pathlib.

A pattern that allows pathlib.Path to be composed with content handling is an
interesting idea. Maybe that should be explored?

But that should be a separate topic.
