I recently found myself needing to use "with", and hating myself for it. Does anyone know a better way to do this in JavaScript?

    // Take an array of context dictionaries, and return a                                                                                      
    // function that evaluates a string in those contexts.                                                                                      
    // I fully realize how horrible this code is, and that                                                                                      
    // it only supports up to ten contexts. I feel terrible                                                                                     
    // about it, as I should, but I would feel even worse                                                                                       
    // if it were impossible to do this. But isn't there                                                                                        
    // a simpler way to do this is JavaScript? Maybe I                                                                                          
    // could use __proto__ inheritence, but I was hoping                                                                                        
    // to avoid.                                                                                                                                
    function evalInContextsFunction(_contexts) {
        var _contextCount = _contexts.length;
        if (_contextCount == 0) {
            return function evalInContexts(_text) {return eval(_text)};
        }
        with (_contexts[0] || {}) {
            if (_contextCount == 1) {
                return function evalInContexts(_text) {return eval(_text)};
            }
            with (_contexts[1] || {}) {
                if (_contextCount == 2) {
                    return function evalInContexts(_text) {return eval(_text)};
                }

[...and so on...]
