This led me to this confusion:

    irb(main):001:0> def each()
    irb(main):002:1> yield 1,2,3,4,5,6,7,8,9
    irb(main):003:1> end
    nil
    irb(main):004:0> each() {|i| puts i}
    1
    2
    3
    4
    5
    6
    7
    8
    9
    nil
    irb(main):005:0> each() {|a,b| puts "#{a}-#{b}"}
    1-2
    nil

Does the number of arguments used in the block (|i| -vs- |a,b|) change
the way yield calls the block?
