Should I leave behind beautiful code or readable code?
To misquote Buckminster Fuller "If the code is not readable it is not beautiful". You can have both readable and beautiful code and that's what I believe we should all aim for- the single map version of your code given by a couple of earlier posters would match my criteria but depending on the context a comment *may* be helpful too.
"When I am working on a problem I never think about beauty. I only think about how to solve the problem. But when I have finished, if the solution is not beautiful, I know it is wrong."
