Markus Unterwaditzer:

Given the following snippet:

```
#!python

'a, b, c'.split(u', ')
```

Result in CPython:

```
$ python2
Python 2.7.8 (default, Jul  1 2014, 17:30:21) 
[GCC 4.9.0 20140604 (prerelease)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> 'a, b, c'.split(u', ')
[u'a', u'b', u'c']
```

Result in PyPy:


```
$ pypy
Python 2.7.6 (3cf384e86ef7, Jul 09 2014, 04:28:24)
[PyPy 2.4.0-alpha0 with GCC 4.9.0 20140604 (prerelease)] on linux2

And now for something completely different: ``samuele says that we lost a
razor. so we can't shave yaks''
>>>> 'a, b, c'.split(u', ')                                                                   
['a', 'b', 'c']
>>>> 

```

I hope the version information given in the shell session is sufficient.
