For a class project a group of fellow students and I implemented
taintness and safe levels in Lua, similar to Ruby and Perl. Work
still needs to be done here and there but I am pretty happy about how
it came out. I setup a webpage for it here. On that page is a
link to the darcs repository, a tarball, and some example scripts.
Also if you want to take a quick glimpse at the changes involved,
there is a diff here.
Feel free to give me any suggestions, code, whatever.
