nl_tokens: make some assumptions about the returning call
pl_tokens: function ( err ) { if ( <mask> ) { defer . reject ( err ) ; } else { //remove the error object, send the info onwards [ ] . shift . call ( arguments ) ; //now we have to do something funky here //if you expect more than one argument, we have to send in the argument object  //and you pick out the appropriate arguments //if it's just one, we send the one argument like normal //this is the behavior chosen if ( arguments . length > 1 ) defer . resolve ( arguments ) ; else defer . resolve . apply ( defer , arguments ) ; } }
