UPDATE: It's a gem!

This helper has finally been moved into a gem called nav_lynx!

Thanks to @brianjlandau and @reagent for getting that set up and tested!

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.
