ISSUES

1. [New comment] cannot import idna from encodings (Ipy 2.7.3)
http://ironpython.codeplex.com/workitem/34651
User paweljasinski has commented on the issue:

"<p>I think there is something wrong in installation/packaging. When I run the ipy out of my development location, it works as expected. When I run ipy out of install dir (c:\Program Files (x86)\IronPython27) it doesn't.<br>I also tried on the separate Windows machine without any development tools installed with fresh new installation of 2.7.5b2 - it doesn't work.</p>"-----------------

2. [New comment] zlib - ValueError: Invalid initialization option
http://ironpython.codeplex.com/workitem/35295
User paweljasinski has commented on the issue:

"<p>workaround:<br>```<br>with open("chunk.gz","r") as f:<br>    data = f.read()<br>import zlib<br>d = zlib.decompressobj(-zlib.MAX_WBITS)<br>print d.decompress(data[10:])</p>"-----------------

3. [New comment] zlib - ValueError: Invalid initialization option
http://ironpython.codeplex.com/workitem/35295
User paweljasinski has commented on the issue:

"<p>workaround:<br>```<br>with open("chunk.gz","r") as f:<br>    data = f.read()<br>import zlib<br>d = zlib.decompressobj(-zlib.MAX_WBITS)<br>print d.decompress(data[10:])<br>```</p><p>The edit button on your own post is missing :-(</p>"-----------------

4. [New issue] built-in translate throws TypeError
http://ironpython.codeplex.com/workitem/35296
User paweljasinski has proposed the issue:

"the following code:
import string
d=dict([(ord(c), ord(c.lower())) for c in string.ascii_uppercase])
print u"A".translate(d)

results in:
Traceback (most recent call last):
  File "translate.py", line 3, in <module>
TypeError: Unable to cast object of type 'System.Int32' to type 'System.String'.
"-----------------

5. [New issue] unexpected behaviour when IOError used as superclass
http://ironpython.codeplex.com/workitem/35300
User paweljasinski has proposed the issue:

"This snippet works in cpython, but fails in iron:
class RequestException(IOError):

    def __init__(self, *args, **kwargs):
        self.response = kwargs.pop('response', None)
        super(RequestException, self).__init__(*args, **kwargs)

class HTTPError(RequestException):
    """An HTTP error occurred."""

raise HTTPError("a", response="b")

the reported error is:
Traceback (most recent call last):
  File "httpex.py", line 13, in <module>
TypeError: HTTPError() takes at least 1 argument (3 given)

when the IOError is changed to Exception, things are back to normal"
