I would have thought that it was a fairly obvious extension given how for
loops work (especially since you can already declare variables in if
statements; you just can't do it and then use something else for the
condition), and it's less verbose than doing something with with, though I
suppose that getting with to work like this would be better than nothing. It
does seem unnecessarily verbose in comparison though.
