Dynamic Function Creation Fails?

I have a small number of functions on an object and for every function I wish to make a different function that calls the original where the this can be passed as a parameter. I am making a library and this is a convenience method for people who don't know about call/apply.

Currently (one of) my function looks like this:

function _find(){
return find.apply(arguments[0],Array.prototype.slice.call(arguments,1));
}

However since my functions are in a object I was wondering if I could make a new array dynamically?

var func = {'find':find}, func_new={}; //this is just an example I don't have this part in my code
for(var attr in func)
func_new[attr] = Function('return '+attr+'.apply(arguments[0],Array.prototype.slice.call(arguments,1));');
