As for typos, there is a reasonable mechanism for catching this present in Lua:

For each script/module you have:
 luac -l <lua-file> | less

Then grep through  *TGLOBAL to catch sets and gets.

Ideally these should be at the very beginning of a module and/or
managed through accessors.  Now... if you have a typo when accessing
members of tables, that can be problematic.. though it's less likely
than typos when accessing items you intend to be in local-scope.
