Actually, I just checked out the latest version of the 1.9 trunk code,
and it seems to have gone back:.

rick@frodo:~$ ruby1.9 modtest.rb
[C, P, M, Object, Kernel, BasicObject]
[C, P, M, Object, Kernel, BasicObject]

I'm not sure why, personally I thought that the way 1.9 used to work
was more natural.
