Thanks for that, never heard of that. Link for anyone interested: http://en.wikipedia.org/wiki/M4_(computer_language) http://en.wikipedia.org/wiki/M4_(computer_language). By the way, I really think that to work (i.e. become usable, maybe even popular), this needs to be built on an existing and popular language. Otherwise it's too steep a learning curve. Ideally, I'd like to be able to put in code in the text file wherever I want, be able to put the value of expressions in the code, and that's it.
