*Unless* I'm mistaken, he was asking for something that returns
the *popped* element?
Re-reading the question, it does kind of sound a bit ambiguous

Woops, of course:
auto popFrontRet(R)(ref R range)
if(isInputRange!R)
{
auto tmp = range.front;
range.popFront();
}
That also invalidates my second point to do with emptiness.
