This shows how different approaches to memoization work (or don't) in different Ruby engines.

Synopsis

If you're using the idiomatic Ruby approach to memoization, like this:

def data
  @memo ||= expensive_action
end

    @noise = chars.split(//).shuffle.cycle

  def censor(text)
    @noise.take(text.length).join
  end

"the government borrows from it... the government could borrow more money to pay it back"

No it doesn't. No it couldn't. Please please PLEASE read up on the structure of the Social Security system before parroting the right-wing line on this. (Did you notice your link here was to an advocate of privatization?)

Social Security payments are made from the current year's Social Security tax. Any surplus collected is, by law, used to purchase (essentially) Treasury securities. This is intragovernmental debt -- it's money the government owes itself. It's actually a huge part of our current federal debt.

The federal government then goes on to spend that money on services like any other revenue. It could potentially sequester that revenue in a fund, but what would it invest it in? What form of savings is more reliable than Treasury securities? You can't just pile up money in a vault somewhere.   So the government doesn't "borrow" from the Social Security Trust Fund -- the government's debt IS the Social Security T
