Lua very intentionally omits 95% of the feature set of Common Lisp, so that you can use it in environments where you only have room for the half of Common Lisp you're using. There are off-the-shelf libraries for a lot of those features, though, so you don't have to use an informally-specified, bug-ridden version.
