Why should it be an error? Fields are not accessed virtually, so there is no hijacking problem. The current behavior is as designed.

If you feel it should be changed, please start a thread in digitalmars.D and present the case.

Posted to digitalmars.D:

I think 90% of the time this happens it is a bug, not by the programmer's intention.

If it's designed to be so in D, I propose to change it; or at least reported by the compiler.

or at least add a compiler flag to warn the user.
