     1.7 +NOTE: During iteration using ``seqlua_iterloop``, ``seqlua_iterloopauto``, or
     1.8 +``seqlua_iterinit``, three extra elements are stored on the stack (additionally
     1.9 +to the value). These extra elements are removed automatically when the loop ends
    1.10 +(i.e. when ``seqlua_iternext`` returns zero). The value pushed onto the stack
    1.11 +for every iteration step has to be removed manually from the stack, unless
    1.12 +``seqlua_iterloopauto`` is used.
