I used to think that, but after some time in python land I 
just finished reviewing the code of a C++ project (about 
5,000 new lines, 7 new classes in a system with 200,000 
lines and about 200 classes.).

I was amazed to discover how difficult it was to understand 
the code because I couldn't identify which variables were 
local to the function, which were instance variables and 
which were global.

This gets worse when dealing with multiple inheritance, 
I wound up spend significant time in the headers directory 
doing grep... The self notation makes it clear and pretty 
unambiguous.
