Dan Webb's talk turned out to be an explication of the JS language, notably the primitives, objects, functions and prototype inheritance. It was good to see those concepts explained in a clear fashion again but at the time I didn't get the link with metaprogramming which Dan defined as:
which was a shame (it's theMetaprogramming is the writing of computer programs that write or manipulate other programs (or themselves) as their data...

as their databit I missed.) Actually, Dan did show examples of using class methods from
Array with other array-like objects (notably arguments), building push methods in implementations that don't have them and a genuine "Meta" addEvent function that self-modified on the 1st call to avoid repeatedly checking for implementation features (namely IE vs DOM2 event model), so that seems to cover the metaprogramming aspect — guess I wasn't paying sufficient attention (or it's a classic example of how taking and writing-up notes can clarify things in your mind.) He finished with a book plug: "The Art and Science of JavaScript", soon to come from SitePoint. (Note to self: get a copy for the library!)
