What languages other than Python have an explicit self?

Question

It seems a bit weird that Python requires you to explicitly pass self as the first argument to all class functions. Are there other languages that require something similar?

Answer 1

By explicit, do you mean "explicitly passed as an argument to each class function"? If so, then Python is the only one I know off-hand.

Most OO languages support this or self in some form, but most of them let you define class functions without always defining self as the first argument.
