Subject: Namespace pollution in Rails

Hi all

I posted a while back about my Rails project having a class called Property
which clashed with the Glue module at Textdrive. They have now removed
the Glue gem and I have changed the name of my class so all is well, but I
still would like to understand how Glue took over the default namespace like
that.

When I ran my script/console on Textdrive I got:

Loading production environment.
 >> Class.included_modules
=> [Glue, PP::ObjectMixin, Base64::Deprecated, Base64, Kernel]

After glue was removed:
Loading production environment.
 >> Class.included_modules
=> [Base64::Deprecated, Base64, Kernel]

How did it take control of the default namespace (and only when Rails was
loaded?) Using irb never gave this problem, and Rails never refers to Glue
directly.
