- values HASH
-
Returns a list consisting of all the values of the named hash. (In a scalar context,
returns the number of values.) The values are returned in an apparently random order. The
actual random order is subject to change in future versions of perl, but it is guaranteed
to be the same order as either the keys or each function would
produce on the same (unmodified) hash.
Note that the values are not copied, which means modifying them will modify the
contents of the hash:
for (values %hash) { s/foo/bar/g } # modifies %hash values
for (@hash{keys %hash}) { s/foo/bar/g } # same

As a side effect, calling values() resets the HASH's internal iterator. See also keys,
each, and sort.
