Improving Python's SimpleNamespace

Especially in complex cases JSONPath is a nice standard for this, it would allow you to write 'clothing.mens.shoes.extra_wide.quantity' here but also supports arrays etc. (like if shoes where an array and you need to find the element in it that has the extra_wide property set to true, and then retrieve quantity from it). I have not yet used it from a Python project, but it seems there are libraries implementing.
