Done.

Since it seems that core Integer, Float, String and Array are sort
of core classes in Ruby, it might also be nice to redefine Object's
to_s, to_i, to_f and to_a to call the long form if it exists. This way the
long form would give the short one for free.

Something like:

class Object
  def to_s
    if respond_to? :to_str
       to_str
    else
       inspect
    end
  end
  def to_a
    if respond_to? :to_ary
       to_ary
    else
       [self]
    end
  end
  def method_missing( message, *args )
    case message
    when :to_i then to_int if respond_to? :to_int
    when :to_f then to_flt if respond_to? :to_flt
  end
end
