You need to use i inside the function to create different closures:

for i=0,2 do
    local a = function() local _=i end
    print(a)
end

But why do you need different functions that do the same thing?
(or should I say same nothing? :-)

Sure enough and it is a reminder that I'm not at the point where I can answer without checking my work[1], even on something I think is simple.

Lua must be checking to see if upvalues are referenced, then?
