equates to your desired code.  Would this help?

Or you could just do

for(; !r.empty; r.popFront())
{
    auto e = r.front;
}

I really don't think that that's a big deal. I don't think that the

particularly when it's so easy to just use for to do the job.

Probably true.  The only one I'd see as being impossible to duplicate is:

foreach(ref e; ref r)
