spot a subtle JS error here..

The other day I ran into weird errors while editing the Y!Mail patch in browser.js. The whole thing stopped working, and it took me a while to see the problem. Can you see it? 

// need to fake someMethod
Element.prototype.someMethod=function(){
    // faking someMethod here
}
// we also have an insertBefore problem so let's fix that too
(function(oF){
    // tweaking insertBefore here
})(Element.prototype.insertBefore);


What was wrong? Hats off if you can see it without running the code.. :smile:

Y!RegExp quiz

This snippet is brought to you by Yahoo!Japan blogs. Quiz of the day: what is the RegExp meant to do and why does it fail?

if(img.match(/(.[jJ][pP][eE]?[gG]|.[gG][iI][fF]|.[pP][nN][gG])/)) {
return true;
}
return false;


(Yes, the variable name is a hint.)
