D - virtual function overrides

One great feature of C# (and perhaps other OOP languages as well) is the
'override' keyword, used to indicate that a given function is intended to
override some function in a base class.  I can't count how many bugs I've
found in C++ code (mine and others') that could have been avoided if this
were supported; it's very easy to change the signature of a virtual function
in a base class and forget to update some derived class, resulting in a
nasty, hard-to-spot bug.  Has some mechanism of this sort been considered
for D?

Yep... see http://www.digitalmars.com/d/attribute.html Override is described on that page.
