Luacheck has two warnings of this kind:

variable x is never accessed — if a variable is set but it is never read in its scope
value assigned to variable x is unused — if a variable is set but its value is re-set before it is read

The latter may need more flow checking, but the former should be more easily doable, similar to how we deal with our "unused variable" warnings.
