If by "loose" you mean "set free", then yes perhaps it will.

(My apologies. It was too good to pass up.)

But instead of seeing goto as a continuation, what if it's a tail-call?

    function A()
      local N=0
      local C=function()
        N=N+1
        goto B
      end
      N=1+C()
      ::B::
      return N
    end
    print(A())

Does this print 1 or 2? Assuming a hypothetical Lua that allows such a thing.
