Wildcards in the pattern for http.HandleFunc

When registering handlers in Go (language) is there any way to specify wildcards in the pattern?

For example:

http.HandleFunc("/groups/*/people", peopleInGroupHandler)

Where the * could be any valid URL string. Or is the only solution to match /groups and figure the rest out from within the handler (peopleInGroupHandler) func?

Here's an example of how to use the code example from @evanshaw

func handleDigits(res http.ResponseWriter, req *http.Request) {
    res.Write([]byte("Digits in the URL\n"))
}

func handleStrings(res http.ResponseWriter, req *http.Request) {
    res.Write([]byte("Strings in the URL\n"))
}

func main() {
    handler := &RegexpHandler{}

    reg1, _ := regexp.Compile("/foo-\\d+")
    handler.HandleFunc(reg1, handleDigits)

    reg2, _ := regexp.Compile("/foo-\\w+")
    handler.HandleFunc(reg2, handleStrings)

    http.ListenAndServe(":3000", handler)
}
