That has been addressed in some many other ways by several languages that goes from the C++ way where you actually have namespaces to the C way where you don't worry about it and pick another name. From all of them I find this the most odd way to address it, specially when python was supposed to improve legibility by design (at least for me those underscores are very distracting)

The underscores are distracting on purpose; any method surrounded by double underscores is one that you're virtually never supposed to explicitly call (there's a builtin `next(foo)` in Python 3, for instance)

Er... they are methods not functions. Tell me how does the C++ way namespace methods within an object?
