You have either to force collect my_function or explicitly set upvalue
to nil. As an option, you may do something like this:
do
local upvalue = { --[[ something large ]] }
function my_function() -- global function
print(tostring(upvalue))
end
function close_upvalue()
upvalue = nil
end
end
But there are other ways to create upvalues. One more example:
local function foo(arg)
return function()
print(tostring(arg))
end
end
my_function = foo({ --[[ something large ]] })
