ISSUES

1. [New comment] Importing .NET types causes ImportExceptions (zipimport handler)
http://ironpython.codeplex.com/workitem/34602
User jdhardy has commented on the issue:

"<p>slide wrote the `zipimport` support, so I'll defer to him on the specification and the implementation details.</p><p>[Lightweight exceptions](https://github.com/IronLanguages/main/blob/master/Runtime/Microsoft.Dynamic/Runtime/LightExceptions.cs) are a DLR feature that IronPython uses to pass exception information without using real .NET exceptions. `zipimport` might need some refactoring to use light exceptions, but it should be possible.</p><p>Unfortunately one has to be careful when using them, as any C# calling code has to be aware that it is dealing with a light throwing function and either be light throwing itself or wrap the call with `LightExceptions.CheckAndThrow`. Functions that are called directly from Python have it easier because IronPython will automatically deal with those and convert them to Python exceptions as needed.</p>"-----------------

2. [New comment] Importing .NET types causes ImportExceptions (zipimport handler)
http://ironpython.codeplex.com/workitem/34602
User sopelt has commented on the issue:

"<p>Thanks for all the info. We would be really happy if there was some way to resolve this situation.</p><p>As a workaround we would even prefer temporarily disabling zipimport support.<br>I had a look at the code but there currently does not seem to be any public api which would allow that (e.g. removing from path_hooks...).</p>"-----------------

3. [New comment] help() commands from StdLib fail/hang
http://ironpython.codeplex.com/workitem/34606
User vernondcole has commented on the issue:

"<p>Owlmonkey:<br>  <br>You should pass this patch on to the python core group.  </p><p>Much to my surprise, an IronPython specific patch of mine was accepted and is now part of the standard library.  My patch was related to the correct operation of "import antigravity" -- yours is somewhat more important. ;-)</p><p></p>"
