- A flag definition (via Bool, BoolVar, Int, IntVar, etc.) will panic if Set has already been called on a flag with the same name.
-
- This change is intended to detect cases where changes in initialization order cause flag operations to occur in a different order than expected. In many cases the fix to this problem is to introduce a explicit package dependence to correctly order the definition before any Set operations.
