eval() is needed only when you want a deep copy. 
use Data::Dump qw( pp dd );

my $ref = [ 'foo', 'bar', { asd => 1, qwe => 2 } ];

# pp() called in void context prints to STDERR
pp $ref;
# prints: ["foo", "bar", { asd => 1, qwe => 2 }]

# dd() called in void context prints to STDOUT
dd $ref;

# named printing is still not DRY, but much better than:
# print Data::Dumper->Dump( [$ref], ['*ref'] );
print '$ref = ', pp($ref), "\n";
# prints: $ref = ["foo", "bar", { asd => 1, qwe => 2 }]

# eval() for a deep copy
my $deep_copy = eval pp($ref);
pp $deep_copy;

The printing format is a lot more readable than Data::Dumper's default. However beware that Data::Dump is not among the core modules.
