nevow.stan uses objects to represent its ast. This isn't the same because it misses the point: objects aren't data in python (or most places, since objects are rarely printable/readable). Practical Common Lisp demonstrates a spiritual predecessor that works on data from 2003[0]. I'm sure there are much older implementations floating around for CL and Scheme but I don't care to look for them. This is a common idiom in lisps.
