but shorter. If you need to force scalar context on the value,
warn Dumper($return);
return $return;
-Another trick that is extremely useful when doing method chaining is the
-following:
+If you need to force list context on the value,
+
+ use Devel::Dwarn;
+
+ return DwarnL some_call(...)
+
+is equivalent to:
+
+ use Data::Dumper::Concise;
+
+ my @return = some_call(...);
+ warn Dumper(@return);
+ return @return;
+
+If you want to label your output, try DwarnN
+
+ use Devel::Dwarn;
+
+ return DwarnN $foo
+
+is equivalent to:
+
+ use Data::Dumper::Concise;

+=head1 TIPS AND TRICKS
+
+=head2 global usage
+
+Instead of always just doing:
+
+ use Devel::Dwarn;
+
+ Dwarn ...
+
+We tend to do:
+
+ perl -MDevel::Dwarn foo.pl
+
+(and then in the perl code:)
+
+ ::Dwarn ...
+
+That way, if you leave them in and run without the C<< use Devel::Dwarn >>
+the program will fail to compile and you are less likely to check it in by
+accident. Furthmore it allows that much less friction to add debug messages.

+=head2 method chaining
+
+One trick which is useful when doing method chaining is the following:
my $foo = Bar->new;
$foo->bar->baz->Devel::Dwarn::DwarnS->biff;
