With that out of the way, I’ll be focusing on 1.2 which will change the API a bit, but will finally add reverse mapping so that you can use it to match request URLs to a URI template pattern. It turns out that this is a bit more complicated than I first imagined. A number of folks have pointed to the excellent wo-furi project as this already does reverse mapping. However, it only handles level 1, and maybe level 2 templates. Things get hairy when you start reverse mapping level 3 and level 4 templates.
