In the spirit of OSS I forked httprouter instead of just keeping the changes locally. I hope that the implementation can prove as a reference in improving httprouter or other Golang muxers.
I like httprouter, but dislike how the dependency on httprouter.Params pollutes your packages that need to expose httprouter.Handle.
I also dislike the non-standard handler, even with map[string]string parameters. From what I read the proper way to "scope" things in Go is to pass "it" as a parameter to a method; so the dislike is just personal preference. Currently the only way to retain the standard (http.Handler) interface compatibility is to use a synchronized reference map e.g. map[*http.Request]map[string]string, similar to Gorilla Contexts' implementation with only the parameters associated with the request.
Anyway, after all those changes it was a short jump to implement basic middleware helpers and expose an initializer with a standard implementation to associate the parameters with the request.
I hope that answered your questions and thanks for showing interest :) P.S. Check the updated example usage
