| Until we get proper lexical scoping, in which case an explicit self
| argument is not only needed, but needs to have the opportunity to be
| different from the enclosing method's self:
| 
|     class Outer:
|         def foo(self):
|             self.x = 1
|             class Inner:
|                 def bar(me):
|                     me.x = 2
|                     return me.x + self.x
|             return Inner

With lexical scoping, we might want to say that all the methods are
"closed" under self:


  class Outer
    def class_methods_here(): pass

    def __constructor__(self, x, y):
      def foo():
        self.dist = sqrt(x*x+y*y)


Then if there are inner classes, we could use a different name for the
'self' object, but we still wouldn't need to have self in *each*
method.. we can define "self" at a new scope level all outside the
methods, but inside the inner class.

Sorry, I'm just dreaming.
