     while i < 5
            print(i)
            global i = i + 1
      end

but... i is undefined in the first line... how can the loop start?

On the line before the block:

julia> i = 1;

.... in the global scope of the REPL.

What's more confusing to me is that `global` was needed in the assignment statement in the loop, but not in the first line in the loop `print(i)`. Why would that be?
