Perhaps, but foreach does not support that.
foreach(e; range)

is lowered to something like
for(auto __range = range; !__range.empty; __range.popFront())

auto e = __range.front;
...
}
Fun fact: an actual lowering from the compiler:
Result __r39 = iota(2).opSlice();
for (; !__r39.empty(); __r39.popFront())
{
int a = __r39.front();
}

(sorry for being slightly off-topic, but it's always interesting
for me to check whether our assumptions for of the inner-workings
of the compiler are true ...)
