 =head2 How do I reset an each() operation part-way through?
 
-Using C<keys %hash> in scalar context returns the number of keys in
-the hash I<and> resets the iterator associated with the hash.  You may
-need to do this if you use C<last> to exit a loop early so that when
-you re-enter it, the hash iterator has been reset.
+(contributed by brian d foy)
+
+You can use the C<keys> or C<values> functions to reset C<each>. To
+simply reset the iterator used by C<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 C<each> in L<perlfunc>.
