My first goal was to write in a wiki using a light and extended HTML. I then discovered LISP and lambda-calculus. I built an "inverted" evaluator working directly on s-expressions (without AST), ignoring words (which therefore did not have to be protected by apostrophes and quotation marks), like in basic HTML. I can thus write wiki pages that are lambdatalk programs, mixing pure text and code effortlessly. It's my all-purpose tool.
