You could also do it the other way around:
after you've loaded your global scripts do

globals={}

function cleanLevel()
    for k,_ in pairs(_G) do
        if not globals[k] then _G[k] = nil
    end
end

for k,_ in pairs(_G) do
    globals[k]=true
end

globals will index all globals present at that point (including itself
and cleanlevel() ), and cleanLevel() will only delete the globals not
referenced there. Case solved :-)
