Hello, 

I was wondering about a change in constant lookup behaviour between the 1.8 and
1.9 lines.

Given following source, which runs fine on 1.8, but will raise:
undefined method `dirname' for Rack::File:Class (NoMethodError)

###################################################################

module Rack
  class File
  end

  class Builder
    def initialize(&block)
      instance_eval(&block)
    end
  end
end

Rack::Builder.new{ File.dirname("foo") }

###################################################################

This is boiled down from a real-world example where i got exactly this error
when running in 1.9. I know i can fix that by referencing `::File::dirname`,
but it would be nice to know definitely whether we can rely on this new
behaviour.
