NAME

       Devel::Dwarn - Combine warns and Data::Dumper::Concise

SYNOPSIS

         use Devel::Dwarn;

         return Dwarn some_call(...)

       is equivalent to:

         use Data::Dumper::Concise;

         if (wantarray) {
            my @return = some_call(...);
            warn Dumper(@return);
            return @return;
         } else {
            my $return = some_call(...);
            warn Dumper($return);
            return $return;
         }

       but shorter. If you need to force scalar context on the value,

         use Devel::Dwarn;

         return DwarnS some_call(...)

       is equivalent to:

         use Data::Dumper::Concise;

         my $return = some_call(...);
         warn Dumper($return);
         return $return;

       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;

         my @return = some_call(...);
         warn '$foo => ' . Dumper(@return);
         return @return;

       If you want to output a reference returned by a method easily, try $Dwarn

        $foo->bar->{baz}->$Dwarn

       is equivalent to:

         my $return = $foo->bar->{baz};
         warn Dumper($return);
         return $return;

       If you want to immediately die after outputting the data structure, every Dwarn subroutine
       has a paired Ddie version, so just replace the warn with die.  For example:

        DdieL 'foo', { bar => 'baz' };

TIPS AND TRICKS

   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 "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.

   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;

       which is the same as:

         my $foo = Bar->new;
         (DwarnS $foo->bar->baz)->biff;
