Message 109245 - Python tracker

I fixed Rev.py in r82550, but I don't think it is worth keeping in the current form.  Maybe it can be replaced with a pure python reimplementation of builtins.reversed.

Note that slicing does not work for Rev:


>>> r = Rev([1,2,3])
>>> r[:]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "Demo/classes/Rev.py", line 69, in __getitem__
    return self.forw[-(j + 1)]
TypeError: unsupported operand type(s) for +: 'slice' and 'int'
