Per spec at http://es5.github.com/#x15.3.4.3 , Function.prototype.apply should accept as its second argument any object with a length property (used as an exclusive upper bound on numeric "indices"). http://bugs.jquery.com/ticket/13282 implies that QtWebKit does not, because passing a NodeList (e.g., from document.getElementsByTagName("a")) fails (confirmed with phantomjs 1.7). In other words, the following expressions should return [0, 1]: (function(a, b){ return [a, b]; }).apply( null, { length: 2, 0: 0, 1: 1 } )
