[pypy-issue] [issue802] Incorrect error message when string split assignment cannot unpack values

[Yesudeep Mangalapilly]

New submission from Yesudeep Mangalapilly <yesudeep at gmail.com>:

Incorrect error message generated when trying to 
unpack values in an assignment:

Current Behavior:
-----------------
    $ pypy
    Python 2.7.1 (b590cf6de419, Apr 30 2011, 03:30:00)
    [PyPy 1.5.0-alpha0 with GCC 4.0.1] on darwin
    Type "help", "copyright", "credits" or "license" for more information.
    And now for something completely different: ``<cami> I like workin with pypy,
    it's like speaking chinese''
    >>>> n, v = "something".split("=", 1)
    Traceback (most recent call last):
      File "<console>", line 1, in <module>
    ValueError: expected length 2, got 1

Expected Behavior:
------------------
    $ python
    Python 2.7.1 (r271:86832, Dec  4 2010, 05:03:53) 
    [GCC 4.2.1 (Apple Inc. build 5646) (dot 1)] on darwin
    Type "help", "copyright", "credits" or "license" for more information.
    >>> n, v = "something".split("=", 1)
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    ValueError: need more than 1 value to unpack


Essentially, the error message needs to be changed.
Some of our in-code asserts started failing because 
of this.
