The answer I was looking for was in fact the multiple assignment comma 
operation.

The original code I was looking at was:

class Timer
  private
  def dispatch
     now  = Time.now.to_f
     ready, @queue = @queue.partition{|time, proc| time <= now }
     ready.each {|time, proc| proc.call((time)}
  end
end
