> pr = Proc.new {|a,b,c| p [a,b,c]}
> pr.yield(1)        #=> [1, nil, nil]
> pr.yield(1,2,3,4)  #=> [1, 2, 3]
> pr.call(1)         #=> wrong # of arguments (4 for 3) (ArgumentError)

# ruby -v
ruby 1.9.2p290 (2011-07-09 revision 32553) [i686-linux]
# cat test.rb
pr = Proc.new {|a,b,c| p [a,b,c]}
pr.yield(1)        #=> [1, nil, nil]
pr.yield(1,2,3,4)  #=> [1, 2, 3]
pr.call(1)         #=> wrong # of arguments (4 for 3) (ArgumentError)
# ruby test.rb
[1, nil, nil]
[1, 2, 3]
[1, nil, nil]
