That isn't the point (if it is true). And actually, C++ stdlib 
uses it. Some C++ devs avoid virtual in general though, but that 
is another issue.

The point is that you need multiple inheritance to unify D 
classes with C++ classes, but you don't have to use it if you 
don' want to, so there is no cost to having it. So basically only 
one big benefit, and no real disadvantages.
