   When using xref:helpers[Helpers], you may want a prefix to be appended so that you don't have to

  ### Route Helpers
  
  Route Helpers provide methods to access defined routes from elsewhere in your code.
  By including the `Helpers` module on the router (i.e. `MyApplicationRouter::Helpers`)
  you can access any helper defined in the router by `{{name}}_path` to get its corresponding
  route. In addition, when you have a `@context : HTTP::Server::Context` instance var,
  you will also be able to access a `{{name}}_url` to get the full url.
