I did use proportional fonts with REBOL, Ruby, CoffeeScript and JavaScript. Tried it with tab-indented Clojure code too. However, 1-2 space indented code becomes just too ambiguous when rendered with proportional fonts, because the spaces are way too thin. I wish editors would render em or en-sized spaces instead, at least for the line-leading spaces. That way we would get the same indentation as intended with monospaced fonts, but still save horizontal space, while maintaining readability...
