You can't have that in principle. No name can ever not be
associated to a value. If you don't do

local v=3

(why on earth don't you?) then Lua explicitly supplies the nil.
Otherwise that slot would contain whatever was in it before
(which may be a user's unencrypted password) and all sorts
of security holes open up.
