title: Register string value for concrete name of parameter
body: <p>I am using Autofac and I have several classes which ask for parameter of type string and name lang. Is there a way to register a string value to all parameters named "lang", so it resolves automatically? I do not want to edit any of the constructors, since it is not my code (I know accepting e.g. CultureInfo would make registration easy..)</p>
  
  <p>Something resulting in short syntax like
   builder.Register(lang => "en-US").As().Named("lang")</p>
  
  <p>would be ideal.</p>
  
  <p>Thank you.</p>
