look at this:

return target.opCmp((cast(ProjectTarget)object).getTarget());

makes no sense...

for the new guys - here is how it should be:

return target.opCmp(object.castTo(ProjectTarget).getTarget());

this was discussed before and Walter is not interested at all.

Your way is worse. It makes D look more like a scripting language than a
programming language, IMO... I guess as long as I had a choice on which method
to use, I'd be OK with it.

Why?  The present syntax cannot be confused for anything but a cast, by 
either a human or a computer.

So why bring it up?

nice! now we just need to be able to provide our Object class
instead of using the predefined.

If it's going to be useful for generic programming, it'll need to be a 
defined method of everything, not just Object.

..and it will segfault/access-violate if object is not some subclass of
ProjectTarget. May I suggest the code should instead be:




or something similar.
