Ok. For the moment I'm just assigning LUA_PATH to package.path. Is that 
reasonable?

Another issue when using -w... how do I check the presence of a key in 
a table now?

For example, I have this piece of code:

         if ( ( type( anObject ) == "table" ) and
                 ( type( anObject[ "equals" ] ) == "function" ) ) then

Which basically tries to check if the given table has a specific key. 
Unfortunately, this raises an exception:

lua: ./LUObject.lua:125: attempt to access undefined variable `equals'

What gives?

Cheers
