--       Old: Packs all the arguments packed, including a "n" field with the number of arguments passed
--       New: Packs all the arguments packed, without the "n" field. Nil values are not permitted
--     find:
--       Old: Finds the argument passed, looping through the numeric keys
--       New: Finds the argument passed, looping through all the keys
-- Functions added:
--     GetDeprecated: Returns a list of functions deprecated for Luau
