  # match evaluates an expr that should result in a MatchFunc where the signature
  # is MatchFunc = func(url.URL) bool
  # There are several functions provided that contain common rules and help construct this.
  # provided are:
  #   matchHostname(...string) MatchFunc
  #   matchHostRegexp(...string) MatchFunc
  #   matchRegexp(...string) MatchFunc
  #   matchAny(...MatchFunc) MatchFunc
  #
  # Note that when using regex, any escapes need to be doubled. Once to escape the string
  # and a second time to escape the regexp char. So a literal `.` is represented as `\\.`
  #
  # For writing custom rules using expr, you can use the following two variables:
  #   hostname: the URL hostname
  #   fullUrl: the full string of the URL
  #   url: the Go url.URL struct that is being called
  #
  # When using those, you can turn them into a MatchFunc using
  #   MatchFunc(bool) MatchFunc
  #
  # For example:
  #   MatchFunc(hostname endsWith "example.com")
  # is equivalent to:
  #   matchHostRegexp(".*\\.example\\.com$")
  match = "matchHostname('google.com', 'youtube.com')"
