Setup

var acc = 0;
    var array = _.range(1000);
    var add = function(a, b, c) { return a + b + c; };
    var iterator = function(x) { acc += x; };
    var mapper = function(x) { return x * x; };
    var reducer = function(acc, x) { return acc + x; };
    
    var fastBound = fast.bind(add, this),
        lodashBound = _.bind(add, this),
        nativeBound = add.bind(this);
    
    var fastPartial = fast.partial(add, 1, 2),
        lodashPartial = _.partial(add, 1, 2);
