4.64: How do I reset an each() operation part-way through?

    (contributed by brian d foy)

    You can use the "keys" or "values" functions to reset "each". To simply
    reset the iterator used by "each" without doing anything else, use one
    of them in void context:

            keys %hash; # resets iterator, nothing else.
            values %hash; # resets iterator, nothing else.

    See the documentation for "each" in perlfunc.

Working code is greatly appreciated.
