When he said "faster access", I think he just meant that the syntax 
makes it more convenient to use them, not that the code runs faster.

Like the way Javascript's object literals make it very easy to use them 
to implement named options to functions, rather than putting this into 
the basic argument processing syntax like Lisp and Python do.
