First off, thanks for doing this!

I'd love to know how much performance improvement we get from writing `Class.prototype['method']` rather than `Class.prototype.method`, when aggregated over the entire life of a request. If it shaves 5% off the request time, great! If it shaves 0.5% or 0.1%, I'd say readability (by which I mean using the standard, familiar syntax) may trump performance.
