 =head1 DESCRIPTION
 
 This module always exports a single function, Dumper, which can be called
-with a single reference value to dump that value or with no arguments to
-return the Data::Dumper object it's created.
+with an array of values to dump those values or with no arguments to
+return the Data::Dumper object it's created. Note that this means that
+
+  Dumper @list
+
+will probably not do what you wanted when @list is empty. In this case use
+
+  Dumper \@list
+
+instead.
 
 It exists, fundamentally, as a convenient way to reproduce a set of Dumper
 options that we've found ourselves using across large numbers of applications,
