+  newfunction(:values, :type => :rvalue, :doc => <<-EOS
+When given a hash this function will return the values of that hash.
+
+*Examples:*
+
+    $hash = {
+      'a' => 1,
+      'b' => 2,
+      'c' => 3,
+    }
+    values($hash)
+
+This example would return:
+
+    [1,2,3]
+    EOS

+
+    raise(Puppet::ParseError, "values(): Wrong number of arguments " +
+      "given (#{arguments.size} for 1)") if arguments.size < 1
+
+    hash = arguments[0]
+
+    unless hash.is_a?(Hash)

+    end

+    result = hash.values
