-The values in C<@_> can either be a list of values or a single array

+The values in C<@_> must be a list of values. You cannot pass the values as an
+array reference, because this cannot be distinguished from passing one value
+which is itself an array reference.
 
 If a parameter is marked as optional and is not present, it will
 simply not be returned.
