Argue determines the argument signature received by a function.

var argue = require('argue');

function foo() {
  var sig = argue(arguments);
  switch(sig) {
    case 'sbnf':
      // we got a string, boolean, number, and function
      break;

    case 'nnnn':
      // we got four numbers
      break;

    case 'ord-':
      // we got an object, regexp, date, and null
      break;

    default:
      // you get the idea
  }
