Considering program > as data are special cases It's the other way around. Considering data and programs as two separate things is an artificially contrived distinction. It's maybe useful for learning how to use some programming languages, but it should be thrown away by the time you want to deal with anything in a more general fashion. The more semantics you have associated with a given piece of data the more easily you can use it to instruct some other piece of data as to what to do with it. Programs that have restricted vocabularies put more requirements on what they will use as input, but ultimately it's all a matter of degree as to what data can be used as a program when and where. Ultimately, there is only the "machine" (virtual or real) and it handles only one thing: call it what you will.... -- Peter Hunsberger
