Hi,
I was playing around recently with building a "stubbing" system in Ruby to allow me to make what looked like "child object" calls but that were really just stubs to methods in the core object.
I thought some people on this list might enjoy this idea - it's just a goof-off kind of thing in it's current form, but it could probably be put to better use with a little attention. My write up is here:

(If etiquette on this list is to post the full article here, just let me know - I didn't want to clog up people's digests).
Happy holidays,
Steve
