cjson.util is used only by the test suite and the json2lua/lua2json scripts. The cjson module seems to work pretty well in a lua5.3 environment, but cjson.util suffers from the move of "unpack" to the table library:
https://www.lua.org/manual/5.2/manual.html#8.2 With the following patch tests "pass" for all three flavors. "pass" because all flavors see the same failure. lua5.3 sees 10 additional failures but they are only due to changes in error messages. I'm currently taking a look at which lua ports support which lua versions, and while I don't plan to add this kind of compat glue on a routine basis, this seems like a low-hanging fruit. ok?
