Class name != file name when using dynamic boo eval

I'm messing with dynamic evaluation of boo and it works mostly fine but so far I can't figure out if it's possible to create and use MonoBehaviour classes that way.

Code (csharp):

1.  
2.         interpreter.Eval("import UnityEngine");
3.         interpreter.Eval("gs = GameObject.CreatePrimitive(PrimitiveType.Cube)");
4.         interpreter.Eval(@"class BooItem(MonoBehaviour):
5.     def Update():
6.         Debug.Log('Boo updater')");
7.         interpreter.Eval("gs.AddComponent[of BooItem]()");
8.  

The code's redundant but it's just for testing. I get:

Since it evaluates from a string I have no idea if this can be solved at all.

Trying my luck, maybe someone can help.
