Why? I consider it a kind of implied parameter. You can reassign self in
Python for example.

class MyClass:
    def foo(self, p1, p2):
        self = 7
        print(self, p1, p2)

c = MyClass()
c.foo(8, 3); # 7 8 3


I can't think of anything else that allows it, though.


If you can change $this, you'll suddenly loose object.

That's what tends to happen when you assign a variable.

I'll have to take your word for it. I just thought the language would be
simpler with fewer "special" things that don't need to be special.
