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.
