So, THAT is what closures are for! :)
Among other things, e.g.:
local function counter()
local aCount = 0
return function()
aCount = aCount + 1
return aCount
end
end
local aCounter = counter()
local anotherCounter = counter()
print( 'aCounter', aCounter() )
print( 'aCounter', aCounter() )
print( 'anotherCounter', anotherCounter() )
> aCounter 1
> aCounter 2
