I agree 'override' adds to the readability, however D already protects you
against function hiding and function hijacking. For example:

-----
class A
{
    void foo() { }
}

class B : A
{
    void foo() { }
}
-----

test.d(10): Deprecation: overriding base class function without using override
attribute is deprecated (test.B.foo overrides test.A.foo)

I don't know why I wrote http://d.puremagic.com/issues/show_bug.cgi?id=2525#c2,
I do believe override makes the code more readable. Ideally we would have an
"implements" keyword, but you know, keyboard bloat and all that.
