[plt-scheme] inheritance of methods

In DrScheme, v205cvs-today, you can write it this OtherLanguage:

Welcome to DrScheme, version 205.3-cvs29sep2003.
Language: Python.
 > class Foo:
     def __init__(self, x):
         self.x = x
     def double(self):
         return 2 * self.x
 > class Bar(Foo):
     def __init__(self, x):
         Foo.__init__(self,x)
     def quadruple(self):
         return 2 * self.double()
 > f = Foo(2)
 > print f.double()
4
 > b = Bar(2)
 > print b.double()
4
 > print b.quadruple()
8
