But he (dave) didn't put any comments to the right of his example, so as long
as there isn't any extra white space to the right of the code, it 
*should* work (on both pre and post ANSI).

Dave gave a good (although yukie) solution to the problem.  He didn't claim
that you could do anything with his solution and have it still work.
