ah, yes, my mistake. I forgot that I was reading old articles. In any 
case I will explain what I was aiming for, and I did mean to use slicing.

while(true) {
    auto subStr = str[0..i++];
    //Do stuff with subStr
}

I just wanted to point out that if a variable is used an the programmer 
wishes to stop the said "loop" when you have reached the end but forgot 
to check, you have a working program that false to work as expected.
