- values HASH

- values ARRAY

  Returns a list consisting of all the values of the named hash, or the values of an array. (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. Since Perl 5.8.1 the ordering is different even between different runs of Perl for security reasons (see Algorithmic Complexity Attacks in perlsec).

  As a side effect, calling values() resets the HASH or ARRAY's internal iterator, see each. (In particular, calling values() in void context resets the iterator with no other overhead. Apart from resetting the iterator, `values @array` in list context is the same as plain `@array` . We recommend that you use void context `keys @array` for this, but reasoned that it taking `values @array` out would require more documentation than leaving it in.)

  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

  See also `keys`, `each`, and `sort`.
