I tried to get typical's functionality by looking for __type, but I forgot to call it if it's a function.  Your typex is harder, since you can't access the registry from Lua.  I could pcall(require) your version, and act appropriately if it's available.

It's not a preprocessor in the sense that Steve suggested, but you do just go "lua -largcheck file.lua" like you do with luacov and luatrace.
