So I think the question becomes: why does Object#initialize accept any 
number of arguments in 1.9? It doesn't in 1.8.

$ ruby -ve 'Object.new(1,2,3)'
ruby 1.8.7 (2010-06-23 patchlevel 299) [x86_64-linux]
-e:1:in `initialize': wrong number of arguments (3 for 0) 
(ArgumentError)
  from -e:1:in `new'
  from -e:1
$ ruby192 -ve 'Object.new(1,2,3)'
ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-linux]
