Subject: Re: Yet another caching mechanism. The one without the cache.

Funny! I didn't even realize that this is essentially the same as the
Once class I wrote just a week ago!

  class Once

    # Privatize a few Kernel methods that are most likely to clash,
    # but arn't essential here.

    private :class, :clone, :display, :type, :method, :to_a, :to_s

    def initialize( target )
      @self = target
      @cache = {}
    end

    def self ; @self ; end

    def method_missing( meth, *args, &blk )
      return @cache[ [meth,*args] ] if @cache.key?( [meth, *args] )
      @cache[ [meth,*args] ] = @self.send( meth, *args, &blk )
    end

  end

So I was looking at the differences with your implementation. What does
the un_cahce do for us?

Thanks,
T.

PS. I like the name Cache better and will use that, and will merge your
implmentation and mine together for Facets.
