Subject: Scope

I have a script with those two following classes:

class String
   def to_b
      ["true"].include?(self.downcase)
   end
end

class HereIWantUseToB
   "string".to_b
end

Ok,  that works fine, the to_b method can be "seen" by
HereIWantToUseToB class. But I wanted to those two classes inside
another class, or module, like this:

class Everything
   # The two classes described above are here
end

module Everything
   # The two classes described above are here
end

Anyway, for both cases I have the message "NoMethodError: undefined
method `to_b’ for string." What is the scope point in here, what is
the best way solve that so ?
