How can I provide a Box subclass that automatically sets default_box=True ?

[marcelloromani]

Essentially I want the user to not have to use this

empty_box = Box(default_box=True)

but rather I want this call:

config = MyConfigClass()

to be equivalent to the former.

I tried subclassing Box:

class MyConfigClass(Box):
    def __init__(self):
        super().__init__(default_box=True)

but that throws this error:

MyConfigClass.__init__() got an unexpected keyword argument 'default_box'

What's the best practice to create a Box subclass with specific non-default values for certain Box options?
