ISSUES
1. [New issue] "from <package> import *" fails, causes KeyError
http://ironpython.codeplex.com/workitem/31305
User mejohansen has proposed the issue:
"Version info:
> IronPython 2.7 (2.7.0.40) on .NET 4.0.30319.1
Example:
> >>> from email import *
> Traceback (most recent call last):
> File "<stdin>", line 1, in <module>
> KeyError: base64mime
> >>> import email
> >>>"-----------------
2. [New comment] "from <package> import *" fails, causes KeyError
http://ironpython.codeplex.com/workitem/31305
User mejohansen has commented on the issue:
"I found a workaround for IronPython
__init__.py for the package must be changed to something like:
>all_modules = ['module1', 'module2', 'module3']
>
>for module in all_modules:
> __import__('%s.%s' % (__name__, module))
Of course, for vanilla Python, it is sufficient to do:
> __all__ = all_modules"-----------------
3. [Status update] wpf module in Silverlight
http://ironpython.codeplex.com/workitem/31204
User jdhardy has updated the issue:
Status has changed from Proposed to Closed.

My guess would be that the debuggable lambda re-writer isn't handling re-use of
the same parameter within different blocks. It might be possible to change
this from calling Insert into using the indexer to assign (which allows
replacements) but that's probably not the correct fix."
