Python has an exact equivalent to the C# method (which uses a new
block/scope for defining properties...)

    class foo:
        class a(Property):
            ''' documentation '''
            def get(self):
                return self._a
            def set(self, val):
                self._a = val
            def de1(self):
                del self._a


Now all you need is a Property base class with a proper metaclass that
handles all of the magic for you.  I'm curious as to why this still gets
brought up when the obvious syntax is more or less identical to
basically all reasonable alternate syntaxes.  Is it because people don't
understand that metaclasses can mangle your class any way they want?
