Holy shit -- I've just found HyperPerl on the c2.com Wikibase Wiki. What an insane concept... for an example check out Wiki in HyperPerl.
Believe it or not, that is executable -- well, it passes through a preprocessor which generates a normal perl script, but the code is extracted from those pages. So there you are -- your code is (very) heavily documented, and due to the way the function references are hyperlinks, it inherently looks like a LXR.
Incredible! What would you call this? Hypertextual literate programming?
