Introducing a block argument here was a mistake. Some people now want the loop index to be a different value. But the worse thing is that the loop index can silently overflow. And if we ever change the language to raise on overflow, this could eventually break some long running programs like servers (and that wouldn't be nice).

while also allowing you to keep the variable inside the loop local to the block.Closes #5975
