Line 1:

local p = {}

local function makeCounter()

local counter = 0

return function()

counter = counter + 1

return counter

end

end

function p.main(frame)

return mw.loadData('Module:Sandbox/Jackmcbarn/data')[1]

local myCounter = makeCounter()

myCounter()

myCounter()

myCounter()

myCounter()

myCounter() -- this returns 5

local newCounter = myCounter

newCounter() -- this returns 6

return myCounter() -- this returns 7, since newCounter and myCounter are really the same thing. is there any way to make a copy of a function that doesn't share upvalues?

end
