Gavin, I just noticed this post and was looking at the project. I currently 
have a library of my own that I call "succ". Now I'm sure many people have 
there own personal libraries, but I have been farily careful with mine and  
it contains mostly only well refined modifications to the Ruby standard 
classes, that I've picked up here and there, and a few new small libraries as 
well. Would those be of interest?

Speaking of which I sometimes think it would be nice if there were an easy way 
append flags onto #require in order to turn on or off certain features. Kind 
of a macro thing. A good psuedo-example of this:

  # succ/nil.rb
  module NilClass

    if Kernel.require_flags[:nil_as_emptiness]
      def to_f; 0.0; end
      def to_s; ''; end
      def to_h; {}; end
      def to_a; []; end
      # ...
    end

    def intern
      self
    end

    # ... other stuff

  end

Then with something to determine default behavior too:
  
  Kernel.require_default = true

  # turn off :nil_as_emptiness
  require 'succ/nil', :nil_as_emptiness

Or

  Kernel.require_default = false

  # turn on :nil_as_emptiness
  require 'succ/nil', :nil_as_emptiness

Or something like that. Thoughts?
