Subject: Delegating a method, with arguments

Hi all,

I'm trying to write a class where I want to delegate some instance
methods as FileTest class methods.  For example:

require "forwardable"
class Foo < String
   extend Forwardable
   def_delegator(:FileTest,:directory?)
   def initialize(path)
      @path = path
   end
end

This doesn't work, however, since FileTest.directory? requires an
argument.  What I would like is something like the following fictional
syntax:

def_delegator(:FileTest,:directory?(@path))

I don't want to create an instance of File and delegate to that
instance because I don't know if @path will actually be valid or not
(among other reasons).

So, would something like this be possible?

Regards,

Dan
