You probably won't get very far by insulting people. Let it be said that the
committee's wise decision to not require an error also helps me in this
circumstance: if you go back to the example I gave in the very first comment
of this PR, then yes, using an object of type 'Y' is probably going to lead
to nothing good. On the other hand, if I never use an object of type 'Y',
then the program may look dubious, but bad nothing is going to happen. 

In other words, Borland's compiler is going to prevent me from compiling
a program that is perfectly fine, is going to do everything I want, and is
going to do that reliably. Is that what you want?
