Ruby 1.9 and the Queue class

[Aldric Giacomoni]

Using Gentoo - just unmasked Ruby 1.9 and emerged it (aka compile/install).
$ irb
irb(main):001:0> a = Queue.new
NameError: uninitialized constant Queue
from (irb):1
from /usr/bin/irb:12:in `<main>'
irb(main):002:0>

What gives ?
If I switch to Ruby 1.8 and do the same thing, I get a new queue..

require 'thread' first.

Governments, if they endure, always tend increasingly toward aristocratic forms.
No government in history has been known to evade this pattern. And as the
aristocracy develops, government tends more and more to act exclusively in
the interests of the ruling class -- whether that class be hereditary royalty,
oligarchs of financial empires, or entrenched bureaucracy.

Do you maybe have some default require which requires "thread"?

Kind regards

Seems like it would be good to put that in it's own require.

require 'queue'

And thread.rb can require that.
