A language with closures, but not as I know them. Is this whole thing with "frozen variables" and percent signs simply a result of not boxing everything?
Does the Lua style of closures have any advantages over, say, the JavaScript way?
The language has some popularity as a scripting language, e.g. in the adventure game authoring system MAD.

How I wish someone would write an adventure authoring system with an interface like the one AGS has, and a scripting language such as Lua (or, even better, Scheme)!

Is there a direct link to something about these closure-like things?

The next version of Lua (5.0, currently available as an alpha release) will have proper closures. Earlier versions did not have proper closures but had a special syntax for accessing local variables from an enclosing scope when creating a function, however the value of these variables was evaluated at function creation time, rather than at function execution time.
You can get more details here http://www.lua.org/manual/manual.html#4.6 and here http://lua-users.org/wiki/LuaScoping
