Bug #1591: DATA handle unusable in required modules
http://redmine.ruby-lang.org/issues/show/1591

I have a Module defined in a file that gets required by a script. Inside the module I set a class variable:

module MyModule
  class MyClass
    @@data = DATA.readlines
    def MyClass.getData
      return @@data
    end
    # ...
  end
end

__END__
lots
of
words
...

DATA is undefined! If I add an __END__ section to the script that requires my module, DATA becomes defined and it contains the data in the script. Obviously the way this works makes DATA + __END__ useless except for the one case where a person wants to access __END__ data from within their own script. I would think the more common case would be a module requires a bunch of data and it is convenient to just put that at the end of the file that contains the module and load it up when it gets required.
