That should be (y.length-1).times { puts "blah" }
The problem with y.(length-1).times is that (length-1) gets evaluated first,
but you can't do dynamic method names that way, so everything will blow up.
Instead, when you do (y.length-1).times, y.length-1 gets evaluated by the
normal precedence rules, so you have (y.length)-1 then you get an integer
out of that, which can then have .times called on it and everything's hunky
dory.
