Too many 'self' in python.That's a big flaw in this language.

Mh, strange, I personally like to use "this.a" in C++, to make clear
I use an instance variable.

NACK, see above.

Explicit is better than implicit.

IMHO, it's also a great hint for the programmer. With others' C++
code, I'm often confused what kinds of variables (global, instance,
static, ...) they access, it's also badly commented. If C++ forced
the programmer to write "this.var", the code would be
understandable with much less comments.
