@script ExecuteInEditMode() in Boo

What is the

@script ExecuteInEditMode()

equivalent in boo?

Also - have anyone ever translated the tutorial project files into Boo?

Here is my script:

import UnityEngine

class NewBehaviourScript (MonoBehaviour): 

    def Start ():
    ...etc

PS: Could you please tag this "boo". I see there is no boo tag here :(

Well it seems this is equivalent to this:

[ExecuteInEditMode]
class NewBehaviourScript (MonoBehaviour):

Looks like C#.
