The key function of a class is polymorphism. But the reality is that in non-tool or container/foundational classes (which are typically write-once, use-lots; you don't tend to write these daily), a typical class will have a couple of virtuals, and a whole bunch of properties. I've argued if no dispatch is needed just make those free functions. You're not going to win many friends, and probably not many potential D users by insisting people completely change their coding patterns that they've probably held for decades on a trivial matter like this.
This is actually part of the point. You keep on discussing as if we design the language now, when in fact there's a lot of code out there that relies on the current behavior. We won't win many friends if we break every single method that has ever been overridden in D, over a trivial matter.
