     1.7 -NOTE: If the index passed to ``seqlua_iterinit`` points to a value that has a
     1.8 -``__call`` metamethod, then the value at the stack position will be replaced by
     1.9 -that metamethod.
    1.10 +NOTE: ``seqlua_iterinit`` will store one extra element on the stack during
    1.11 +iteration. When ``seqlua_iternext`` returns 0, this extra element is popped
    1.12 +from the stack automatically.

    1.14  Additionally, ``seqlualib`` includes a function ``seqlua_iterclosure(L, idx)``,
    1.15  which converts a table at a given stack index into a function closure (stored
    1.16  on the same stack index) that iterates over the elements of the table. If the
    1.17  value at the given stack index is already a function, it leaves the value
    1.18  unchanged. If the value is convertible to a function using ``__call,`` then the
    1.19 -value is replaced by its ``__call`` metamethod.
    1.20 +value is replaced by a closure calling the ``__call`` metamethod.
