1. [New issue] ScriptScope.TryGetVariable<>() throws exception if item isn't string.
http://ironpython.codeplex.com/workitem/33918
User Thaumaturge has proposed the issue:

"This is a snipit of my test C# code...
         source = "NewThing = 1.234";
         pySource = pyEngine.CreateScriptSourceFromString(source, SourceCodeKind.AutoDetect);
         pySource.Execute(pyScope);
         string strTemp;
         if(pyScope.TryGetVariable<string>("NewThing", out strTemp))
         {
   
         }

This is the exception I'm getting.

Is there a better way to do this, or wouldn't it be better to return false than throw an exception?"
