I'd be very careful about giving them the same name if you're working with IE at all. IE8 and below's JScript does some really strange stuff with function expressions, leaking and hoisting them all over the place. [1]

Instead, I'd just append a character or something to differentiate the two. I've been using the format advocated for in Javascript Patterns[2][3]:

    var foo = function fooF(){};
