If we use the approach of converting var's to named parameters, we also have to give up on passing variable numbers of arguments to functions. That is, unless we do something silly like: function silly(x, y, z, args) { args = Array.prototype.slice.call(arguments); args.shift(); args.shift(); args.shift(); args.shift(); x = y = z = undefined; // regular function goes here }
