I think Delphi, as well as C++ and Java all
allow this.

By the way, shouldn't it be this:

class abc: Object, xyz  // Inherit from Object
{
    void doSomething()
    {
        // do something
    }
}

Or is Object automatically assumed as ancestor
when the first 'class' in the inheritance list
is in fact an interface?

I thought it does as long as the implementing
method is defined as public or protected?
I can hardly imagine this would not be possible!
