Iterating over an array reference

# data $bug
{ 
 'keyword_objects' => [ 
    bless( { 'id' => 15, 'name' => 'CRASH'}, 'SomeModule::SomeFilename' ), 
    bless( { 'id' => 6, 'name' => 'CUSTOMER' }, 'SomeModule::SomeFilename' ) ],
 'category' => 'error'
}

   foreach my $keyword ($bug->{keyword_objects}) {
     print Dumper($keyword);
   }

It prints the whole of keyword_objects instead of the individual items in it. Now it should be obvious to you that I know so little about Perl, I'd like to also ask what is the right way to reference name in each keyword.

To iterate over the elements in your array ref, you need to dereference it. foreach needs a list.

foreach my $keyword ( @{ $bug->{keyword_objects} } ) {

Your objects are hash references, so you could reach into their internals like this:

$keyword->{name}

However, messing with internals is not a good idea. Instead, you should write accessors and call them as a method.

$keyword->name
