PEP 3134 -- Exception Chaining and Embedded Tracebacks

Although I can compile the code, it seems tokenizer does not understand the from statement in a raise clause as per PEP3134.

A dummy sample code :

  try:
    pass
  except Exception as e:
    raise NameError from e

IronPython throws syntax error: 

  File "", line 5
        raise NameError from e
                        ^
SyntaxError: unexpected token 'from'

Yes it seems the same, I did not notice it has already been raised.

By the way, I am very happy that support/development seems to be awakening as per Jeff posted on mailing list.
