Subject: mod_ruby namespace question

Hello,

In mod_ruby, if I try something like:

  class String
    def foo
      self+'foo'
    end
  end

  'hello '.foo

then I will get an exception, because I was extending (well, creating, I
think) a new class called String, but it isn't the same String as, say:

  'hello '.class

I was wondering if this is intentional, or a side-effect of something else?

I can get around by doing something like:

  fooDef = <<END_FOO
    def foo
      self+'foo'
    end
  END_FOO

  'hello '.class.module_eval fooDef

or even just:

  String.module_eval fooDef

Am I not supposed to do something like this?  (I'm guessing that this would
add the foo method to every string in all of my scripts, which is fine for
me if that's the only 'gotcha'.)  Or is that something in mod_ruby which
should be fixed?

Thanks,

Chris
