If there is another, even more general way than foreach-on-delegates, it 
may or may not, be better than foreach-on-delegates and make it 
superfluous. But as D currently stands, foreach-on-delegates is not 
superfluous, or less simple to the language. I find the otherwise: it is 
quite natural and better than using mixins hacks (even if the difference 
isn't that much). I've favored this feature ever since Oskar Linde(I 
think it was him) made some posts about using different kinds of 
iterators in foreach(using that wrapper hack), and the idea that the 
language itself could support it, like it does now.
But as for foreach_reverse, I do agree that it is very superfluous and 
way, way specific.
