This makes it easier to e.g. subclass classes should one need to (e.g. as I needed in #212), and to access data from outside (while being mindful of the fact that you're accessing notionally private data).
Only one change to a test was required (and that test was indeed accessing a private field from outside and had to jump through hoops 😄 ).
This will avoid Python's class-name-prefix mangling of attributes and methods while still retaining the signal that they're meant for private use of the library.
