I think you missed the point.
The fact that this can happen - even if you make it illegal, means more
maintenance. Using it from libraries also means that simply adding a
member to a library could cause untold number of users to that library
have compilation errors.
Besides, this was a "real" problem with a Pascal program I wrote many 20
years ago and why I never used the 'with' keyword since.
