• Supports required, optional, regexp and wildcard slots
• Smart slot delimiters (e.g. can match /{from}-{to})
• Well-tested with 100s of tests

  r.Insert("/{owner}/{repo}/{branch}/{path*}", "repo.html")
  match, _ := r.Match("/matthewmueller/enroute/main/enroute.go")
  fmt.Println(match.Route) // /{owner}/{repo}/{branch}/{path*}
  fmt.Println(match.Value) // repo.html
  fmt.Println(match.Slots[0].Key, match.Slots[0].Value) // owner matthewmueller
  fmt.Println(match.Slots[1].Key, match.Slots[1].Value) // repo enroute
