Have you looked at Python's standard library? IMHO, it is written in a very
OO style, and yet, the Python maintainers seem to get over that "lots of
typing". Since most Python programmers read the standard library to find
Python idioms (or they should -- it is Python code written by Python 
experts), most people tend to follow that style.

It is just as informal as in C++, only C++ pretends otherwise...

Depends on what part of "Python" you ask. Pythonic security mechanism
(e.g., those built-in to Zope) can surely use things like leading 
underscores for security.

Note that Knuth regrets adding "protected" to C++. It would take a 
really bad Guido day to add a feature that the C++ designer regrets <wink>
