woops, what i actually meant is that noweb doesnt work. I was thinking about it, and it might be possible to
(a) automatically create overlays around begin_src blocks using auto-overlays
(b) have a custom syntax parser that parses noweb syntax in those blocks. Sort of like what is done for syntax highlighting.
Im gradually converting my code to literate programming and am just on the verge of splitting up my one clojure ns to one-block org file into multiple blocks per ns, so i will soon need the noweb functionality. When i get it ill make sure to post and update!
