Use callcc for non-recursive factorials.

factorials_in_cc.rb

require 'continuation'

class FactorialsInCC
  def fact(n)
    factorial = 1
    callcc { |fact_jmp| @fact_jmp = fact_jmp }

    factorial *= n
    n -= 1

    @fact_jmp.call if n > 1
    factorial
  end
end

puts FactorialsInCC.new.fact(ARGV[0].to_i)

Hah, not yet. At least not in Ruby. In Ruby, I think callcc is a solution looking for a problem. A good use case may not actually exist.

That's exactly what I said!!

Did not! Er, where?

I told you it was a trap!
