meta.rb
# meta.rb
# Access metaclass via a fluent notation.
require 'facets/functor'
module Kernel
# Provides access to an object's metaclass (ie. singleton)
# by-passsing access provisions. So for example:
#
# class X
# meta.attr_accesser :a
# end
#
# X.a = 1
# X.a #=> 1
#
# The fact that some class methods are private and thus inaccessable
# via use of metaclass, is really a problem with them being private --which
# is probably not really neccessary. Short of making them public though, thiere
# is this method or one could use the #instance functor.
#
# TODO: Don't see any reason this can't go into core, but there is
# a conflict with URI prior to 1.8.6, so it will have to wait.
