[IronPython] CustomSymbolDictionary question

So, if I understand this right, you have user code, which you need to run each time first ... and then your code which you want to run once after. Something like:

// when your app starts, or something, compile your code, but don't run yet
var compiledCode = engine.CreateScriptSourceFromString(code).Compile();

// do other stuff ....

// execute user code
var userScope = engine.ExecuteFile("usercode.py");

// run your code in the user's code's scope

Subject: [IronPython] CustomSymbolDictionary question

Hi all,

I have a situation where I need to run a script many times with a different scope each time.  I want to be able to substitute an instance of a class each time it is asked for.   For example,

x = MyCSharpClass()

Using CustomSymbolDictionary I am able to store the class created on the first call and then substitute it for every additional call to x from different scopes.  While this works to provide the same class instance to every scope, a new class is being created on every call and replaced with the original class.  Is there a way to only create the class once.  The script will be user code so I have no prior knowledge of variable names and such.  Any ideas would be appreciated.
