Using refinements in the sandbox.

[ghost]

Hello,

I was wondering if it was possible to use refinements within the sandbox.

For example, given this module:

module FooRefinement
  refine String do
    def to_s
      return "bar" if self == "foo"
      super
    end
  end
end

Would it be possible to somehow inject that into the sandboxed code so that when I run this:

s = Sandbox.new
priv = Privileges.new
priv.instances_of(String).allow :to_s
priv.allow_method :puts

s.run(priv, 'puts "foo".to_s')

It outputs "bar" instead of "foo"?
