I believe his point is that Python, unlike every other language he can
think of, requires "self.x" instead of just "x". Every language needs
a way to say "current object", but not every language needs you to say
that for every member reference. C++, Pike, and Java let you
short-hand that. (They're all deriving from the same syntactic style
anyway.) JavaScript doesn't, I believe, although its variable scoping
rules are some of the most insane I've ever met, so there might be a
way to shortcut it. If your experience of OO is mainly from C++/Java
family languages, then yes, Python will seem odd.
