On Ruby 1.9, use BasicObject.  On Ruby 1.8, use Jim Weirich's
BlankSlate object.   I recently ran into an issue with blankslate
though where it was incorrectly revealing methods, so you might want
to use my patched version:

Take this with a shaker of salt though, I mainly modified the example
to show off certain dynamic programming techniques in my book[0], and
not necessarily to make it robust.  I have emailed Jim about these
changes, but he hasn't gotten back to me yet.
