If the task becomes more complex then I would almost certainly rewrite the code with more explicit control structures and descriptive variable names rather than jump through hoops making the map fit. I am only throwing away one line, when all's said and done.

I agree with your comment about CGI and said as much at the top of my post, which was more a comment on the code snippet itself and it's legibility rather than it's suitability for parsing CGI.

Cheers,
