pyobjc-framework-Cocoa/Lib/PyObjCTools/Conversion.py is using Foundation import *
from Foundation import * takes 5 seconds on my machine, now with the new lazyloading i'm on the steps removing all that in the app I'm working on, to speed up loading of the app.
But I notice
import PyObjCTools.Conversion has still
from Foundation import *
so was one of culprits i found.
