You can make it more simmetrical (and slightly more verbose), declaring
both at the same time, and also use explicit assignments, I think this
would reduce the chance for errors:
local func1, func2
func1 = function ()
...
func2()
...
end
func2 = function ()
...
func1()
...
end
Using explicit assigment solves the "look like a global" problem, as all
the globals in your code are probably being declared in the usual way. :-)
