#index would be a problem because we don't know at compile time if index is an 
integer or something else. The whole point of this would be to fast-track 
access to elements in the argument list.

Rather than add line noise, could we elevate select to a keyword? Or perhaps 
produce an optimizing compiler that knows how to inline the function.
