From http://digitalmars.com/d/2.0/statement.html#ForeachStatement, "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 And is the spec a bit out of date in the examples?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Those names are indeed out of date.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. - Jonathan M Davis
