It looks to me like everything in the `for` loop behaves like
variables inside a `let` block. Yes, one could argue that a `for` loop
variable should always be a new variable, making it equivalent to
let i
for i = itr
...
end
end
but that does make the constructs less orthogonal. In any case I don't
see how this is "do or don't, it depends". Depends on what?
