Along the same tone, httprouter doesn't allow defining these routes simultaneously

    users/:id
    users/watching

Was kind of surprised as we have many routes like that. Like gorilla/mux, I think it was just first (trie-based mux). Isn't gin based on httprouter?

There are even better muxes now. `pressly/chi` is used by heavy hitters in production and takes advantage of Go 1.7 HTTP context. `labstack/echo` is another highly recommended by others but I don't like the non-idiomatic echo.Context in handler signatures.

Back on topic, I hope the go web examples only imports built-in packages. The gorilla/mux example could easily be written to use built-in packages.
