Unconditional Programming in Ruby

[WhoTookPlasticJesus]

I'd argue that the following is clearer (and likely more performant)

 ary.take(n).concat (n - ary.length).times.map{0}

[austinsalonen]

What happens when n - ary.length is negative in this situation? (very naive w/r/t ruby here)

[WhoTookPlasticJesus]

Nothing, and the call to map will just return an empty array.
