I find the first form the be more intelligible with less effort than the second form.  I
am an extreme newbie to Ruby, though experienced in several other languages.

I would prefer that the code in example 1, if in a real program, use a different local
variable, but I did understand with little effort that it was intended to be a local
variable.  Any other choice would have increased my surprise.  Several languages that use
an approximately equivalent form also require that tie loop control variable be local.  I
think that the languages that don't make this choice are in the minority.  And deservedly
so.
