"Foreach over Structs and Classes with Ranges".

I read this as the Range design is a part of the language now. Is this 
correct?

And is the spec a bit out of date in the examples?
It says foreach-/reverse translates to

for( auto __r = range; !__r.empty; __r.next /* or __r.retreat */)
	auto e = __r.head; // or __r.toe

Should this be the following?
for( auto __r = range; !__r.empty; __r.popFront /* or __r.popBack */)
	auto e = __r.front; // or __r.back

Those names are indeed out of date. It's another thing that needs to be fixed
in 
the docs.
