Somehow..

foreach(i; foo)
{
    auto x = i[0];
    i[0] = x + 1;
}

You often say that operator overloading should be used only what it should 
be used for, and taking the index of an iterator means.. what exactly?

Would it be nicer to just use a .value property instead?

foreach(i; foo)
{
    auto x = i.value;
    i.value = x + 1;
}
