2010 02 24 messing with number prototype

@rcanine shows us this interesting this coerce behaviour within the prototype of Number. Fun!

    (1) === 1; // true

    Number.prototype.isOne = function () { return this === 1; }

    (1).isOne(); // false!

    Number.prototype.reallyIsOne = function () { return this - 1 === 0; }

    (1).reallyIsOne(); // true
